    Could you tell me on which video? the Wattage is important indeed, but also the watt/kg... 

    some interesting reading on https://support.kinomap.com/hc/en-us/articles/217526666-How-is-calculated-the-bike-speed-in-the-training-apps- but also on https://www.cyclingweekly.com/fitness/training/the-importance-of-power-to-weight-and-how-to-improve-yours-164589. It hope it clarifies.

    Best

    This a tricky but interesting topic. At present, the way it works on Kinomap is that we get the wattage sent by the console. and move you according to your speed depending on the wattage and incline. Some equipments give very fancy and optimistic power. when you do 50watts, it tells you on the console 100 or 150W. Some machines have a spin down calibration to reset the wattage to a reasonable value, most don't. Shall we consider 50% of the wattage shown on the console ? It can be very frustrating for the user. Shall we say this brand or model is not accurate at all ? It can be also very frustrating for the user. 

    When the data are too suspicious, we don't show it on the ranking. 

    We are about to change also the ranking to let the user looking at all participants or just see the ones have the same model or at least the same brand than him. If the data are not accurate, at least it should be consistent a bit between the same models or same brand (assuming they use the same provider...).

    When you train on your own, you can be past participants who made it before. As for the ranking, we will preferably pick up some having done the same video than you, having exactly the same model than you or at least the same brand if we can't find enough having done that video on the same model.

    It hope it will bring more clarification and accuracy. If you have other ideas or suggestions, please let us know. We will be pleased to implement something different in order to reflect the reality as best as possible.

    Regards from Kinomap

    Hi folks,

    I agree with Reinhard.

    I'm using the Sportstech ESX500 and driving with ~ 317 Watts on the track 'Observatory Hill'. As a beginner I will not be able to reach such values :)

    Same for some rowing sessions (for example 1574517) - There are users which finished this in 3-4 minutes?!

    I think it's crucial for kinomap to find a good balance of all devices, so that this remains fair and the motivation accordingly high.

    Hey Philippe,

    thanks for your answer.

    Yeah, it gets very difficult if the manufacturers don't use a uniform standard. I like your idea to see result based on the used model or brand.

    And yes, I saw the result of the 'fast one' not shown on the ranking - Thanks for clarifying.

    Dear all,

      

    Was kind of puzzled too by the high watts I produced during my kinomap rides. Only my indoor max watt power seemed consistent with my outdoor power data.

    Then after discussing with other cycling performnace experts my 200+ watt difference between indoor and outdoor rides, my/our focus to explain difference went on the cadence produced indoor. Average cadences of 120+ /minute are a lot higher then what I can achieve outdoors.

    When doing now kinommap rides limiting my cadence to 100, 90 or even 70/minute i am completely unable to reproduce even 300 watt or 60% my highest avg watt performances (500+ watt). The difference with my VO2 max and other powertest then becomes less then 50 watt average. 

     

    Remaining question:

    Is there a manufacturer device inaccuracy when calculating power output based on cadence ?

     

    Hope this helps

     

    Kind regards
