HIE understanding

I can definitely get a breakthrough with repeated short hard efforts with short (about 30 sec) rest intervals say 3 hard (150% TP) then one really hard (say start at 200% TP and hold as long as you can) and I can almost guarantee a breakthrough will happen. But try to hold 125% of TP and I can not get MPA to decline before I am unable to continue…so that is the equation I am trying to crack

On this one, if Xert’s modeled power doesn’t closely align with what you can do (when fresh, motivated etc) it is possible that your signature is not dialed, and it maybe worth getting support to take a look. The algorithms are not always perfect (and / or maybe they’d say the data going in is not always perfect )

On a related note, I recall @GoustiFruit had issues holding 95% of TP for 4x8 minutes per previous forum posts (see front load periodisation ones), despite being able to have a BT on Ronnestad style efforts. Not sure if that was ever clarified but sounds similar to what you are seeing.
