@rob@rar, good point.
For me, I really enjoy carving and that’s going to be my focus, but I’ve also decided this season to improve my off piste powder skiing. So if I get the chance and there is some powder I will be trying that. It’s tricky as I love carving so much and rarely want to do anything else.

Just some feedback.
The current top scores are moguls indeed, but that’s because they are literally some of the best skiers in the world. Number 1 is Olympic silver medalist!
Let’s see how scores even out once resorts open properly.

I also noticed that the top skiers on the global leaderboard now are moguls skiers. I know you can filter on skiing type, to me, having an overall global leaderboard across all disciplines doesn't make too much sense now as they're such different skiing styles and techniques now.
Unless it's me not looking properly, it seems as though there's no longer the leaderboards you can create, the Snowheads leaderboard seems to have disappeared now.
It seems as though 160-169 is now called Shred Zeppelin. I'll get working towards that next week as long as my replacement sensor has arrived! |
Are you concerned that in chasing ever higher IQ scores you are going to focus on one type of skiing, where you are most likely to score more highly, to the detriment of your broader skiing skills? Seems to me that there's a potential downside in terms of "valuing what you can measure, rather than measuring what you value" if Carv scores begins to dominate your skiing. |
No I'm not concerned, as I'll only be chasing CARV scores on the times I'm skiing and conditions allow. I.e, nice weather, first thing in the morning on freshly groomed pistes. I'll be skiing all conditions throughout the season at all times of the day.
If I look at the data in the app, I used it 22 times last season, but I skied around 80 times, so only around 25% of my time thinking about this one specific strand of skiing.

I think that's a good way to use it. Specific measurement of a specific thing, but not letting that dominate your skiing overall.

Surely once the algo gets good enough you should just be able to leave it on all day and let it rate you based on the terrain and skis you are skiing. It's encouraging if it's rating moguls highly that it has got beyond pure carves as the only thing it can really model.

Sure, if you don't change your skiing behaviour, that would be fine. But the whole gamification element of it, because it can be very addictive, could easily change skiing behaviours and intentions.

Was 137, now 131 
Interestingly there seems less variable in max / min ski IQ across ski days. So I lost my high of 137 which was on a nicely groomed Orange in Tignes, but overall all my scores now seem around 130 with a high of 131.
Lots of work to do!

I think with the new way it works I'll be more likely to just put it on most days and just let it run in the background and see how it looks at the end of the day. With no need to stop and gamify the 8 turns any more it'll totally change my use of the device.

That's exactly what they've done for this year.

Seems to have settled on 146 for now, every year it drops and have to really work at it to get back up again!!

@KenX, yup. It starts populating at your early years first. I was watching my rating go up with each season and it settled on 140.

what do people think is the best way to start with CARV?
we'll be skiing a few weeks this year and I'd like to see some measurable improvement. is it just to stick it on for day 1 and at the end of the day see what it suggests for improvement?

@richb67, so I just had it give feedback on lifts and score when I stop.
Why not start improving from day 1?

@PisteOffice, that is a fair point. It's difficult to know how you'll use something effectively until you have some experience of using it.
My thinking was it will take me the first morning to get my legs back and I probably don't want constant critique during that process! also, I assumed it would function better with more data so it would only have the first afternoon to generate that. Finally there is some Mrs B "management" involved in this, I'm pretty sure I'd be in the dog house if I kept stopping on day 1 to look at my phone or don't chat when we're on the first lifts

@richb67, so, the thing about Carv is it doesn’t tell you off. It’s all positive encouragement. So don’t worry about that.
The lift feedback is only 30 seconds long so won’t be a problem and the wife won’t even know! You’ll get a better feel for it when you start using it.
You can also turn on active coaching which gives you more info after every turn.
Enjoy it!

Still a couple of things to analyze in the new app, but it looks cool. Lost 12 points though.

No problem at all! Just a different reference system and a different way to calculate the SkiIQ. My level is the same as it was the last day of last season.
I think the biggest change is in the way SkiIQ is calculated for a given run of a certain style. According to Carv's blog:
"Last year, Ski:IQ was based on the median of all your individual turn scores; this year, we take the median of your underlying metrics first and calculate Ski:IQ from that profile - making the score far more consistent and interpretable."
So, if I'm not wrong, what it does now is:
To keep it simple, let's suppose we only have two metrics: Early Edging (EE) and Turn Shape (TS). Let's suppose also that the algo uses a 2 best turns rolling window (instead of  . Now, let's suppose we have a segment of 3 carving turns (and that 3 turns is enough to get an SkiIQ). Considering this:
Window 1:
Median_EE_W1 = median (EE_T1, EE_T2)
Median_TS_W1 = median (TS_T1, TS_T2)
SkiIQ_W1 = f(Median_EE_W1, Median_TS_W1)
Window 2:
Median_EE_W2 = median (EE_T2, EE_T3)
Median_TS_W2 = median (TS_T2, TS_T3)
SkiIQ_W2 = f(Median_EE_W2, Median_TS_W2)
Segment_SkiIQ = Max(SkiIQ_W1, SkiIQ_W2)
I've just checked with one of my segments, and it makes sense. SkiIQ for each turn:
121, 125, 127, 129, 134, 134, 137, 138, 144
Applying last year algo, SkiIQ should be 134. Applying a rolling top 8 to the SkiIQ, it should be also 134. However, the skiIQ for this run is now 131 (which is a score I did not get for any of the 9 turns individually).
What are your thoughts?
|
|
|
|
|
|
|
|
|
Another curious case. I have run with 14 turns with a Ski:IQ of 125. However, in the turn by turn analysis none of the turns is higher than Ski:IQ=124

Looking back at my scores, my previous best was a 157 from 23rd March, that's now dropped to a 152, my new best score of 155 is from 30th Jan which at the time was a 154.
It seems as though the way in which they calculate the SkiIQ is having more of an effect than the way 8 turns are calculated for me.

I’m wondering if the individual turns are worked out before weighting the steepness or other factors? I will try and enquire with the peeps.

Does the algorithm take account of slope steepness? Perfectly carved turns on an easy blue is a much easier task than perfectly carved turns on a steep red.

@rob@rar, As far as we could see last year, the only way to get a high skiIQ was on a steep slope.

@doddsie, thanks. It would be nice of Carv published the exact criteria used when they calculate the scores for different types of turn and terrain.

@doddsie, I agree, it ends up being a game of trial and error, trying to work out what you have to do to score highly.

@PisteOffice, The metrics tell you what you're getting low marks for, but improving a metric doesn't mean your skiIQ will improve. The only way to work out how to score highly, is by looking at the high score on the global leaderboard and trying to work out which metrics actually matter, they certainly aren't all of equal weight.

@rob@rar, You're more likely to build bigger angles on a steeper slope vs a blue slope, and that'll help improve the scores for sure.

Yes, for sure, but it’s also possible to get very big edge angles on a gentle slope. You’d hope that a steeper slope has some sort of multiplying effect?
Looking at the app it references slope pitch in some places, eg ‘Dialling up the G-force’, so I guess there’s something in the algorithm which calculates steepness, it would be nice to know though.

Having spent a couple of days with junior using my CARVs last season and seeing how high he could score, it was all about slope steepness. Quite simply the steeper the run, the higher the score. The only other thing that would have helped would have been better snow and according to the US forums hero snow increases your score considerably.

@tangowaggon, your best bet is to just ski with it the first day and see what it says at the end of the day, and from then on decide how you might want to use it. If you're skiing with others you might struggle to work on the drills etc so might just be better freeskiing and listening to the tips it gives you on the lift
