Despite what many people may think, BT’s actually wont become easier or more difficult to achieve based on how high/low the PP parameter is. PP gives an anchor to where MPA will sit when you’re fresh, but it’s depletion is (almost) purely based on TP and HIE.
For example, if we ask an athlete with 20.0 kJ HIE and 250 W TP to do an 8 min effort and his PP is 700, you can see that he would be expected to hold 315 W for 8 min before a BT would be reached:
If we take the same athlete’s HIE and TP and now change PP to 1200 (a huge 500W difference!), that same athlete would now be expected to hold 316 W (0.3% increase in power) for 8 min:
