Aiyh...well you know it's well-rounded then. ^_^
Perhaps you could check the maximum values for the stats on Smogon/Serebii, and see which are closest....
Or...(can't believe I didn't think of it earlier, xD), soft-save and use the EV-reducing berries. One takes them down to 100(assuming it's above 100), and the next 90, then 80, etc. all the way to zero. Do that with each stat, and see how far they go before it says the stat can't go any lower. ^^
