First Time I've Seen This
My car apparently goes to 11...
I recognize this is a rounding issue but ABRP has always rounded down by 1% relative to the car's display - presumably better precision and/or a decision to round down for anything lower than the full number value. So 100% on the car normally shows as 99% on ABRP.
