My gen time motivation is different as to why I want to keep it short.
First, there is the campground time limit of 9-11am to do my 50-90 so I don't want to slow down the recharge half way along as I was worried the Flash procedure might require. I think I now see how that really works.
Second motivation is where in a different campground in summer we are allowed gen from 10am-2pm. This is lots of time to do my 50-90 but I don't want to be stuck there battery charging all that time. Once it is done I am free to go up to the lake for a swim :) So get the gen recharge over with ASAP.
Solar in summer means hardly any gen time needed at all, so more swimming or whatever.
