Have you considered posting in the request leaderboard moderation thread ( https://www.speedrun.com/the_site/thread/dueac/83 )? Before you do that though, SubOptimal has a Twitch, YouTube and Discord linked and I suggest trying with those first.
Also congrats on the sub 9 :) I haven't recorded any runs but I did get an 8:52 on the 12/6/19: https://imgur.com/keEVKy8
How about discord? I know he was active on there around a year ago but no idea since then.
I haven't watched your run yet but if you think sub 8 is possible I'm excited to get back to running this.
Recorded a few Beta Contact runs and two Any% runs today, I feel like I've mostly derusted. Here's my new Beta Contact PB (see other thread about the in-game recording function): I think the main timeloss over the WR is at the end.
I also have an 8:55 Any% which I haven't uploaded yet. It wasn't very good but at least a verifiable sub 9.
Update: video now up and run submitted
@Merl_ Your 8:17 and 8:16 actually beat the radius mode WR now lol (8:17.930 - https://www.speedrun.com/mobility/run/zp42l78z )
Today, three new PBs. Any%, getting closer to the sub-8:
Beta Contact, getting closer to the sub-7 but I just can't nail that strat at the end:
Beta Radius, a pretty good level to speedrun, sub-6 is possible:
Three any% PBs today Less than 2 seconds away from the sub-8 now, mainly from dying on Ultima and not pausing while the boss falls:
Also did some Ultima Radius, will probably go for a low 7 in the future:
