bmi*** hip/waist/chest drift

[ID86s]

bmi270 and bmi160 drift all the time at hip, waist or chest, even if you swap with another one that ain't drift that much.

About drift: it just turning in right after 4 min or so (i asked about 20 people about it and they have same drift to right as me)

I tried slime vr versions v0.12.1 - v0.13.2 (except v0.13-rc.4 and v0.13.1), even talked with alot of people in russian and english vrc community about that issue and most of them have it

sorry for my bad english
