It usually only takes me a few seconds to measure. Think about what two things your measuring and plan out before raising your arm. Its actually really good to develop your eye to try and guess by eyeball what the ratio of one measurement will be to another. Its something I do naturally beacuse Im lazy and dont want to spend time measuring. Being able to look at two points and pin point the middle, break the segment into thirds ect... But yea maybe exercise your arms more. I dont know about your condition but pushups and lateral raises might help.
