I've never been very good with the stadimeter. Stationary target, take three readings and get three different measures... lol - so add the 3 together, divide by three for the average. Or get anal, and do fiive, throw out the high, throw out the low, add the remaining and divide by three... Or do a fast-90 and be done with it... lol - big thing though, is using the correct ship in the RecMan, AND having accurate mast height data...
