I find that you do not request data about player training progress. How can you know whether a players is fast trainer?

In old version, training progresses and condition consumption can be checked after each training sessions or matches. I am not familiar with new version. I don't know if training progress can be checked in new version.

In my opinion, it is difficult, if not impossible, to find a formula to accurately identify fast trainer. Great variation of ratios for player with different qualities is the biggest problem. We also lack important information like contract end date for analysis. However, with information like player age, value, & quality, we can reasonably identify fast trainers.
