Reinforcing what has been said, and it should be obvious now, WKO isn’t going to predict your TTE. Rather it is just giving a number based on the (90-day) PDC. Don’t feed really short power max efforts for 90-days and your TTE will increase as the model decays at the left side of the power curve. For example I recently had some hard 1-5 second efforts fall outside the 90-day window:
and when those stronger <5-sec efforts fell outside 90-day window my TTE increased.
