I pretty much agree with that. I tested 3x last year (Jan 4th, end of Nov while tired, the following week while fresh) just to have concrete confirmation progress is actually happening. The thing about those tests is if you do them right there's no way you're doing more than 1x5min + 1x20 min above z2, and that seems like a waste of a workout. I'd rather have 3x20's scheduled since it's more time in zone.

I think there is value to someone performing the test the first few times because like what [MENTION=89743]jdms mvp[/MENTION] said you do learn how to pace them properly to maximize the e-wangage and it helps to have a reasonably accurate number to base things on, but beyond that only a very occasional test makes sense to me.
