I think what is most important in a
stress test, is evaluating how hard your
heart can work before problems occur, and identifying those problems. It is also important that you CAN reach your optimum, or there is definitely something amiss. I had no idea it was on a time based thing, to me that would be like a race. Every stress test I've had, the operator has always said "ok I will now speed it up a bit more" or "It will now increase in incline".
