There were quite a few discussions on time constants on the Wattage Group forum (requires membership in the group).hmronnow said:Concerning the time-constants, has anyone experimented with them?
How were the 7 and 42 day constants established?
If they were the result of analysing some statistics from multiple riders, what was the spread in values for different riders etc?
In other words, how likely is it that different riders should have to adjust these time-constants? and if so, what could be a protocol for doing so?
If I understand correctly, ATL-time is the timescale on which the FATIGUE from a training session fades, and CTL-time is the timescale on which the BENEFIT from a training session fades?
(Obvously if you want to adjust a 42 day time-constant you need to spend multiple 42 day periods to have enough data.)

right. leave 7 and 42. adjust the values below them.frenchyge said:So... just to be clear.... you're talking about the "seed values" rather than the time constants?
The seeds are just a way to estimate your starting load for exactly the situation you have coming off a mountain bike with no PM and moving to off season road training with power data.kaparzo said:right. leave 7 and 42. adjust the values below them.
