Hi,
If you don’t require a lab test, I would be happy to help with the maximal runs.
I have a very good idea where my AeT is, AnT should be in a range of 5bpm. DF Alpha1 works really good for me and I can provide these values for both runs instead if you like.
Just out of curiosity, how are you trying to do this? Simple regression?
I might have something for you: https://youtu.be/Am0fnK2A0aY?si=lzT66Z_–sjG-y2p
It’s in German but maybe translation works here.
