Honda 2000: surprisingly poor oil fill tube design

My over fill/spill came filling first time when new. Mine was filled at factory, run/tested, then drained before shipping. I went by amount in manual, to fill, and second guessed a small amount of residual not drained at factory. I guessed right on after break in, when draining refilling, due to knowing exact amount, that was just a bit much. I did catch every last drop in my small pan, so yes, measuring the exact amount in pan would work well.
