We've reprocessed all of your historic data in line with our new Ski:IQ Nevado Algorithm. This will be the algorithm calculating Ski:IQ this season. The algorithm is normalised so the majority of people stay the same, most people only change by 1-2 points, but a few scores may go up or down by up to 10 points. If you're disappointed by the change - we are sorry because we know how hard you worked for your scores! However, it’s important to update your historical scores to give you the best view of your progress season after season. We prioritize your improvement above all else - and if we can process your old data more accurately and give you a more accurate sense of your skiing, we choose to do that (even if your scores go down from last year). Hope this all makes sense, but please do let me know if you have any further questions!

This year, we’ve changed our turn detection algorithm to require a minimum of 8 turns. This was previously 6 turns. If your segment only has 6 or 7 turns, you may no longer see a Ski:IQ for this segment.

If you are still having issues, please swipe left with two fingers and select ‘Report an Issue’. Our customer success team will then be in touch as soon as possible.

All of your historic sessions will be reprocessed in line with the new Ski:IQ. Your sessions may take a few minutes to download from our server depending on the speed of your internet connection and the number of sessions on your account.

By default, your Carv app will download via WiFi. If you would like to download via Mobile Data, head to More > Data Syncing > Mobile & WiFi.

You will not be able to see pressure in the latest version of the Carv app.

Our first generation, Carv 1, utilised foot pressure measurement and, with a good setup, it accurately measures the underfoot pressure through the boot. However, retrofitting perfectly to every ski boot with a simple installation is challenging, and the result is the quality of data between boots varies significantly. The result is historically we have had to carefully treat the pressure data to mitigate for the discrepancies.

Despite the improvements we made, we found motion-based metrics to consistently outperform those from the pressure sensor, even when measuring forward movement of your centre of mass. By focusing on motion data, we’ve made a breakthrough—Ski:IQ Nevado is now more accurate across all conditions. With enhanced balance metrics, pitch detection, and snow surface identification, we're delivering the best data yet, and these improvements are available on both Carv 1 and Carv 2.

We found that acceleration data is very useful because it has a high correlation with the way you lean forward and back during the turn in relation to your skis.

The Early Forward Movement & Mid-Turn Balance metrics look at the changes in acceleration along the length of the ski (fore aft). Our interpretation of them involves making assumptions about the movement of the COM constrained by the dynamics of skiing.

1. Early Forward Movement measures the percentage of fore aft acceleration increase that happens in one movement during transition. Our interpretation of this is that when you project your centre of mass diagonally over your skis in transition (Early Forward Movement), we measure how your skis catch back up with your Center of Mass.
2. Mid-Turn Balance measures the percentage Fore:aft acceleration decrease that happens in one movement during the turn. Our interpretation of this metric is that it measures how fore aft acceleration decreases after the skis have caught up & past the centre of mass, creating grip along the full length of the ski.
3. Turn Transition / Vertical Pressure Release measures the percentage of vertical acceleration released in turn transition. Our interpretation of this metric is that when you are able to be weightless in transition, this metric will be high.

Progressive Edge Build is now Mid-Turn Edge Build, the metric is the same but the name has changed to indicate that the metric is focussed on the middle part of the turn.

Edge similarity is now Edging similarity - this metric is the same but the name has changed to indicate that the metric measures the similarity in the rate of change.

Early Forward Movement - this is a new computation based on acceleration, but a similar concept to the prior version based on pressure.

Mid-Turn Balance - this is a new computation based on acceleration, but a similar concept to the prior version based on pressure.

Transition Weight Release - this is a new metric measuring acceleration in the vertical plane during the turn transition.

Outside Ski Pressure, Pressure Smoothness, and Early Weight Transfer have been removed.

One of our main goals this year was to simplify the product experience because feedback from our users was that Carv was hard to navigate and it was challenging to know which feature to use when. Train with an Olympian was a wonderful mode, but we took the ethos of it (stepped levels of difficulty) and integrated it into the 'turn by turn' coaching, which has the added benefit of adapting to the snow type as you ski.

This season, you can choose from audio feedback presets to achieve the same coaching as we previously had in Monitor modes and Active Coach. Want to hear something different? You can further personalise your coaching experience to suit you. Just hit ‘Start’ to begin recording your runs, you’ll get Ski:IQ scores and Tips as you ski, and you can customise the Audio Coaching you receive at any time.

We are currently working on a progression pathway that shows your improvement over time, inspired by Train with an Olympian, but it will have a wider remit than just carving skiing.

There are a few steps to calculating the Ski:IQ. Firstly, it's important to understand what a segment is, it is all the turns from the stretch of skiing beginning when you start to move and ending when you come to a standstill. How we calculate Ski:IQ on a segment:

1. For each turn we calculate metrics (e.g. max edge angle, edging similarity, but also metrics that are responsive to the difficulty of the slope you are skiing). We combine these metrics into a Turn:IQ.
2. After that we discard turns that are well below your ability in the rest of the segment. These are often your first and last turns and will appear as grey dots on the map.
3. The Ski:IQ of your segment is the average (median) Turn:IQ of those remaining turns
