I am using a 2nd generation yeast (Wyeast 1762) from a brew that was about 1.052 and repitching it, after it has been washed and made into a 1 liter starter, into a 1.062 beer. I have always heard that when reusing yeast you should pitch up. I was wondering if that was enough of a gravity difference to prevent any off flavors. (The 1st generation of the yeast was used in a 1.035 brew.)
