I have recently done a lab lactate test on a treadmill. I had purchased one of the mountaineering plans two years ago and done consistently aerobic training for the past 18-20 months. Initially, I did an HR drift test and estimated my AeT to be 135 bpm. I train on an incline treadmill, not running, and on average I trained for 3-4 hour per week, each session being 50-60 minutes. These are the results of my lactate test.

HR     Lactate

81       0.8
93      0.8
104    0.8
117     0.9
130    1.6
141     2.4
152     4.1

So is it correct to say that the AeT is between 117 and 130? In the past months, I mostly aimed for  an average of 125-130 HR during the session, but sometimes it drifted to 135 later in the workout. Should I scale back and train at an HR closer to 120? After 18 months, I was expecting to see an increase in AeT over my initial estimate of 135 based on a HR drift test, but maybe I overestimated because of wishful thinking…
