downside would be having potentially every current record redone but instead just in -30 grav.
and these records would probably just be retaken by whoever has the 9.82 version of the record.
having higher grav just raises the difficulty. like a hard mode version of the record. a record’s grav isnt what appeals to everyone.
in a tournament, yes, there wouldnt be any grav restrictions to appeal to all replaymakers. this isnt like replaymaking though, and doesnt require any style at all. -30 grav vs -9.82 is sortve just a stylistic choice, not an entirely different playing field and wouldnt warrant another version of the BoR imo
