So at best, the formula is a complicated one to figure out so far, if its actually strictly formatted that is.
I have usually received similar Win amounts to Mac's formula, however, I have always noticed discrepancy's as well.
I usually register 3 wins for shooting the Zep.
Now although It seems to be standard to get 3 wins for Bomb The Carrier, I have also received only 2 wins.
Same with capture the carrier, it seems to be standard to receive 3 wins, but I have also registered only 2.
Most often I receive 1 win for Bomb the base, but there have been times that I have also received 2 wins.
I have made multiple efforts to find the differences, such as, paying close attention to how many times I've bombed the enemy base, made it back to base, and reloaded, and how many kill's were accumulated while doing so, all without a clear understanding of how, and why the discrepancy occurs.
One more thing regarding the 5 wins for a single game,
I have won a game, checked win amount prior to entering the next game, noticing that the win did not register in stats, after winning the next game, both wins, for both games then register in stats at the same time, as obviously the stat for the previous game had been delayed in registering until the second game had been won.
As I have been curious about this particular subject Myself for quite sometime, I thought I would share just a small sample of my experience with it.
