Had a captain freak out because we hit 31 kts while distracted by something else. Had me help him formulate the exact wording for the ASR. a week or so later saw him filing another ASR. Probably files one every time he farts.
Were you or him taxiing? Just a thought given that if you were distracted and managed 31kts..what was the distraction? Granted the ACR's border on the ridiculous at times, but taxi speeds are a no brainer, its not like 30kts sneaks up on you.
Personally I wouldn't file an ASR for 31kts, but unless I had a brake failure I wouldn't get close to that speed unless I was on a runway...brake wear be damned.
