Is the goal of the targets it hit AND HOLD the power target for the entire minute? Or, if I simply hit the target but fall back slightly,have I achieved the target?
No, you need to hold the target in each step as long as you’re able.
…and as soon as you’re unable: STOP. The ramp test is now over.
I don’t really understand the “fall back slightly” comment. Are you doing it on s dumb trainer? On a smart trainer, the ramp portion of Half Monty is meant to be done in ERG mode. So while your cadence could slow (which would result in a modest, temporary reduction in power until it stabilized), ERG doesn’t have a fall-back-slightly feature. When you can’t stabilize your cadence quickly, that means you’re done with the ramp.
Your answers make perfect sense. Thanks.
