Wow. what a colossal waste of time and resorces. Why on earth would you want to keep track of time hours? People put in what they want to and what they can. To expect them to do more is ridiculous. To say anyone has done too much is also ridiculous. You cannot get good results by forcing peole to do work in FIRST. Commitment level is not something that needs to be that precicely measured or that should be measured in hours.
Going on trips is based mainly on work hours, but also on grade level, if it your last year you are more likely to get to go etc.
