The current Community SOB using the best IL times from all runners is at a 59:19.15. Breaking the 58 barrier still has a long way to go. However, the BTT sheet, a sheet combining the best segments between moon grabs, is at a 57:51.75.

Yeah, this jump was found a couple months ago. Not until recently it has been viable for runs due to the setup created for it. Currently, the fastest route is to do the normal route, skip the shop moon, and then warp to the Odyssey at the end to do the jump. It saves about 5 seconds with using the first person setup and 9 seconds optimally without the setup.

The first thing I would do is get each of the small broodal bosses consistent. Missing a cycle on any of them usually loses about 6-10 seconds. The other main thing is getting your movement cleaner and adding small optimizations over time. Just try a couple strats you've seen that save a couple seconds and see if you want to add them to the run. But don't add too many at once, maybe one or two in each kingdom. Overall, it's up to you how you practice and there's no set way to do it. Do what you feel comfortable with.
