Yeah, it seemed a little ridiculous to me when I did a stress test. My MHR is way above what the "know-inaccurate tables predict" so basing the test off of 85% of that low number results in a test at a really easy effort. I may be wrong, but it didn't seem like enough effort to stress the system much at all. I wasn't even fully warmed up yet. The doc seemed to think it was an impressive test for a middle aged guy (that was decades ago, I am well past middle aged now).
