tap delay inaccuracy

I’ve noticed the Tap Delay function is very inaccurate. Anyone has noticed this or has a work around?
I always tap 124 or 136 bpm! I want to be in between!
The only way to get in between is to scroll to it by hand. Is this a problem with my desk or does everyone have this? Any work around? i mean thats 11bpm! Thats huge!
