I doubt I'll ever use oval rings so that's not the issue. Not having a chain come off vs. 3W over 12hr is the issue :)
3 watts should be 2-2.5 minutes so how quickly can you hook a chain back on?
Plus the slowing->stopping time and the acceleration time and then there's the rage... and that's if it happens only once.
