I tested again today(15%@2.0mph) as you suggested.  This time I got a drift of ~3.4%.  I felt like I could maintain nasal breathing as long as I focused on it, and the RPE felt more like a conversation pace than last time, but I did notice a bit of fatigue start to build in the last 5-10 minutes.

If I understand this right this means the top of my Z2 is the “starting HR for the test”.  My HR average from minute 5 to minute 10 was 115.  Giving me the following:

Recovery 88-104

Aerobic Capacity 103-115

Anaerobic Threshold 116-?(haven’t done the anaerobic test yet)

Does this look right?

As someone new to structured CV training should I test again in a month or two?
