Using Training Peaks to Analyse AeT Test

I’m just did first AeT Test. I’m trying the do the part where I compare the average HR for the first and second half of the test. When I select the first half of the test, instead of getting a display of the stats for that portion, I get a pop up saying that I need to get a Premium account.

Am I missing something or do I need to now to get a Premium subscription to get these numbers?

If so, is there another option out there?

Thanks!
