So you can fill the Total XP for the rank 44, if you are on rank 43.

I don't understand, what you mean by the "it is basically impossible, at this point in the game, to get accurate EXP ranks without only playing round 1 over and over". You can get accurate XP requirements of the next rank. It is just the sum of those two numbers (one of the numbers is increased by 1 with every bloon popped and the other number is decreased by 1 with every bloon popped so the sum is always the same on the same rank).
