Special Scenarios. In certain circumstances it might make sense to violate the usual rule of thumb about doing all of the floors you can and then saving advancement. This is especially true when you reach high levels in the ability. Suppose you just completed a run of flooring 1 through 27, but wind up around 500 XP shy of being able to do flooring 28. Should you reset, your prestige will be locked at 27, and that's the figure which will be averaged together with your floor numbers for floors 1 through 27 on your next run through Daemonheim.
But if you do flooring 27 again, even though you'll get zero prestige on it for the repeat, you'll then have sufficient XP to level up. You can then conduct floor 28lock in a prestige of 28. Then, when you return to floor 1 and begin a new streak, you are going to be receiving XP according to that higher prestige quantity of 28, instead of 27. The excess XP you make it over 27 flooring employing a higher prestige figure may be more than you gave up by copying a floor.
