So I ran into that same issue. Won’t bore you with the actual numbers. So what I did was just repeat the same AeT test 2 weeks later. The issue for me was I had alot of stress with other things going on and did not approach my AeT test very well rested. Not sure if that is a factor for you.
Either way if I am unsure about the numbers or my effort during a test I will repeat it with the exact same grade and speed so I have several data points to make a decision. Hope this helps.
