Well not exactly a potato per se, but I do check my stats often. Basically though I care little for ranks (It's easy to become a high-ranked bomber, but very hard to become a high-ranked fighter), but more for the stats. I like the fact that stats are reset for each tour as this helps me mark my progress. Mostly I use stats to see in what areas I need improvement--the areas that aren't immediately obvious while actually flying--and, likewise to see if I might not be so good in a certain plane as I think. Are you a stat potato too?
