I don't think this is on the spreadsheets, but I am wondering, what if someone used the -3.27 pattern instead of the normal -7.12? Would this be allowed? (because I want to use this pattern, I seem to get optimal BBG like every single time)

I don’t use the spreadsheet. I use the screenshots file because it covers about everything I need. To more directly answer your question, yes, that should be fine.
