I was just playing 10/20 Pre-Patch casually, when I accidentally got 9% again AND I did it 1 attempt after 7% run, so I did 10/20 Pre-Patch not only 2 times in a row, but also both runs were done with really high %s left. I also messed up a bit with Bidybab there 2 times, but even if I hadn't, it still wouldn't have been 10%, so it doesn't really matter.
Also I did it using Low Detail Mode in order to keep game in 60 FPS.
My previous 9% run was done without LDM, thus handful of people consider it invalid, so I'm happy that I now have 100% valid 9% run. Even though my 1st 9% win was verified, I still wasn't happy about that lags, hence I wanted to got it again without any lags.
Might go for 10%, but I'm not sure if I will, because Ballora RNG.
Run done on 60 FPS and on 'Sister Location Definitive Edition v1.03' with LDM and Pre-Patch power drainage enabled.
