Only 2 maps have sure optimizations:

Farm: Nearly a second from a slightly alternate route, difficult to replicate. (Verified Possible.)

Collector: Nearly half a second from just being overall better. (Verified possible, has been done without a recording.)

What maps are incredibly optimized:

Bank: At this point, Bank can only be improved by faster pickups. An alternate route or glitch has not been found to improve times.

Jewelry Store: This run might be one of the most optimized maps out of all 7. The previous WR was a 10.540. It took practically 2-ish months to lower to 10.530. It could be possible to be much quicker, but until then the WR runs for this level might be extremely difficult.

Home Invasion: Home Invasion has reached a point where the route is most likely the fastest route. The only way to be even faster is a good code and even better pick ups.

Yacht: This one is incredibly difficult, however can be improved. This one run has took an extreme amount of attempts, and it's difficult.

Diamond Heist: The zleed skip/clip has seriously changed the game and has allowed the WR to go from 1:35.300 to 56.800, which is absolutely INSANE time save. However, the glitch is A) difficult to pull off B ) repeated twice. Because of this, expect minimal time saves. (at most, 1.20 seconds, as of 8/6/2021 10:34 PM Central Time Zone)

I mainly uploaded this so people can choose which runs they would like to attempt the most, and what would be easiest and what they would like. If you want recommendations on where to start, I would say Bank or Diamond Heist, as they are relatively easy to speedrun casually.

Update 1: Diamond Heist

also if you find the collector jump hard you can just go to the window to the right of the balcony and climb that, its only about a second or two slower but can help you focus on the run inside the house

what's the alternate farm route?

The alternate farm route is a glitched jump from the side stall things, run into it and jump and you get a glitched jump, requires you to go to the side first however.

i've found a possibly faster route on farm by ~.5ish seconds (not the route above but can be used alongside for an even faster time)

it's inside the house where instead of getting the package on the counter aka the first package you pick up, you go striaght to the shotgun room and pick up 3 stacks of money on the table with the shotgun and go on your run as usual. you could also pick up three from the barrel behind the door in the corner but it's slightly slower. it's slightly faster as it is directly in the route and requires no detour of the optional route

yeah man dia heist i destroyed ez

lmao

wait i realized threads were a thing
