B-screw tension, Shimano 12 speed

[Philly G]

Hi everyone, question about derailleur position, shimano 12 sp. I bent my derailleur hanger in an unscheduled dismount. Ive straightened it, and I'm taking the opportunity to tune my shifting as well. I've always adjusted my b-screw so there's a 5-6mm gap between largest cog and top cage pulley. But the gap on my Rail is easy 3 times that. Doesn't seem right? Anyone else have the same? 6mm allen key in the pic for scale

My bad, just downloaded the manual. For my set up, gap is set by lining up the tooth on the largest cog with the line marked on the pulley cage. Mine needed tightening a couple of turns
