map_settings.enemy_evolution.destroy_factor question

[TheSAguy]

What is the formula to determine the Evolution increase for destroying a spwaner?

In 0.12 it was:

Code: Select all

game.evolution_factor = game.evolution_factor * destroy_factor * (1-game.evolution_factor)

I thought I read in the release notes of 0.13 that it's now:

Code: Select all

game.evolution_factor = game.evolution_factor * destroy_factor * (1-game.evolution_factor)^2

I tested the above and it does not appear to be correct.
Thanks.
