bgb 1.5.9.w64SR - Happy enough with this run now (timer stopped late, but final time appears to be 15:31.89). 15:2x is possible, but I will leave it for now with the 1-cycle Smogger. Sum of best at the end of grind was 15:17.9. Apologies for dropped frames in Dust Area, my laptop has not been able to local record while streaming at this time.

TAS completed this run in 14:15, so it's questionable if there is a remote possibility of getting sum of best down to 14:xx or even find a way to get this time close to that mark. Time saves could be made with faster Sulfura and Contaminous fights, but otherwise it may come down to developing faster stage sections.
