Variable Turns?

[Soldier]

Real life has got nothing to do with this issue. This is a game issue as relating to a balanced game and more so, the same exact conditions must apply to each and every game, using the same scenario.
The scenario conditions can not change from game, etc.. (especially the time length alocated for victory conditions) to game.
How does one compare his scenario results to others that played the same scenario, if one set of players game goes for nine extra turns, etc.
You can't compare those two, because they're not the same scenario anymore, based on a different number of turns per game.
Even one extra turn can make a difference.
