PINs easily pinched with iPhone-attached thermal imaging kit

Would a 4 digit PIN with two repeating digits yield more possible combinations for the cracker to test in this situation than one with four numbers as there's more uncertainty (you wouldn't know which of the three was repeated)?

It would suddenly get a lot easier with two repeated digits (like, as it happens, my wife's PIN) though.
