Simple math says that if, on average, 15-15 will yield a 50-50 split in who suffers a tank loss, then once that happens,

and the sides are 15-14, one would expect the side with 14 to have a greater than 50% chance of the next tank loss. And if that happens, and the battle is now 15-13, an even greater likelihood of suffering the next loss, and so on and so on. It doesn't often happen that a game goes 15-0 because of natural variation and randomness, but the snowball trend in a match is built into how casualties occur.

In other words, even matches shouldn't go 1-0. They should tend to blowouts. How much? An interesting mathematical exercise that someone (other than me) should do. (you could build a statistical decision tree for each combination: 15-15 down to each possible end result (from 15-0 to 1-0). But however you define blowouts (15-5 or less, or 15-2 or less, or whatever) the simple math (once one side has an advantage, that advantage should grow) suggests that blowout are entirely expected.
