Following lineandinitial's point, also depends on where the midpoint for your new band is compared to midpoint on the old one.
For example,
If you are at 115% of 75k midpoint (or 86.25k), then if your new midpoint is 80k, you are now at 107.8% (86.25/80).
The greater the variance between current and future band midpoints, the more your compa % will decrease.
