Still a lot of work to be done, but this is the start of it. We’ll have a few new inputs/variations into it from the findings of the PhD so far. Likely turn a few parts into slider vs typing so UI is faster. And to expand this for full sessions and a few cool things

Setmana Valenciana- W'bal Insights. Asides from the fact my PhD is based around this. I find it often paints a nice narrative of what happened. Hard push on 2nd to last climb, pace was hot on the last then eased. Then saved themself for final Sprint, with a few up the road.

@andrea_zignoli @Athletica_AI We’ll share in the paper when it’s finished all data collected. Particularly all the physiological changes that were captured through this study. Some interesting findings too. Some findings will hopefully be at cycling science again.

@jem_arnold Protocol was 40s on 20s off then into a TTE after a set amount of work was completed. Then 2 minutes very easy and then into the same work rate until failure again. These have not been fully solved, but shows the differences. We have clear differences between fresh and fatigued.

Tour of Oman Stage 5: W'BAL profile of two riders. Both finished well. Other a good few places ahead. After W'bal is close to 0, it hovers low with slow recovery. They were unable to maintain the set pace, and continued around ± CP until the finish.

@jem_arnold We can to a few ways to solve for it. This one will have two parts fast and slow, just in the early stages. So red and blue are both during the same session. Red completed first then blue around 60-90 minutes later.

@jsolalo Thanks - hopefully a few more insights to come from this, as this is just a small snippet. We also look at how intensity plays a role.

Chrono Étoile de bessege - TT W'bal insights #3 different variations for 𝜏w', showing differences. This was a well paced effort. Climb to finish. Also need to consider technical ability with speed/corners. Consider which 𝜏w' you use - Paper on this hopefully out soon.

Insights into W'bal - TTT Volta a la Comunitat Valenciana. 7 Start, need to finish with 4. How do you pace it and use riders wisley? Where is most optimal? How well do you actually recover and how deep do you go. Here is a single profile, you can do much more though ;).

In addition torque production could be something to consider as well

@Di_Bach @spragg247 @peter__leo We are currently writing a criterium paper, obviously slightly different but it will demonstrate some insights into what you can do to build a reasonably informative picture.

@Di_Bach @spragg247 @peter__leo Hence the rationale for our current study.
