160 is quite a reasonable AeT. We have had very well-trained young athletes with AeT heart rates up into the high 180s. These kids had max HRs of well over 200, though.

The drift test usually correlates very closely with a gas exchange test. If you have done this test several times and keep getting the same result, I think you can be confident that your AeT is around 160.
