Okay, checking potshot which can be finished around 2 minutes 50 seconds, you can get any pay out you want, and its pretty clear the 3.1 and the 4.1 payouts are the most rewarding, but which one is the better of the two?
On the surface they're almost identical.
With 60 minutes of grinding, you can get:
Seems like it doesn't matter which you choose right? Well kinda wrong. Once you factor in waiting times(on a 16x potshot playlist) there is a slight difference between the two.
My wait time, from the cutscenes in the mission, and the lobby waiting, it runs around 1 minute 13 sec.
The 3.1 can be completed 20 times in the 60 minutes (not including wait times) so when you include the wait times, the time to earn $146,200 is 82.6 minutes.
The 4.1 reaches 146,250 in 76.95 minutes.
So from what we see, if you are a serious number cruncher and want the absolute effecient way to grind potshot, you are best to finish in the 4.1 range.
But if you are just grinding and a few couple thousand really doesn't matter to you, then either the 3.1 or 4.1 will be fine.
If there are any flaws or better ways to complete this mission, correct me, i have this playlist but i don't know how to find other playlists for other missions so this is what i will be grinding. Thanks
