I just did the Anaerobic test modified to 20m on a stair mill.

I did a 15m warmup and then took a few-minute break to drop a layer and have some water.  I was pleasantly surprised that breathing, not quad burn was my limiting factor.  Maybe my muscular endurance is ok.  I bounced between L5/6 and managed 65 floors climbed.

Looking at the data I noticed that it took my HR 5-6 minutes to fully ramp up.  If I use the entire 20m test my AnT=135.  If I use the last ~15m(after my HR ramped up) I get an AeT=139.  Which should I use?
