HD I think what he is saying is that His days in the feild vs ducks harvested will complelty skew the results... as such he doenst want to send them in...
Most of the rest of us have a more "Normal" days in the feild vs birds harvested ratio...
I know One of my old professors Roger Renolds that taught at CWU had something like a 30 year hunter per bird day average of 5... All on public land All half day hunts... Not to bad when you figure that there were a lot of years with a 3-4 bird limit. 
Problem with statistics is one person can hunt only one day and get 7 ducks 4 geese and now they have 11 birds per day season. I'm sure a lot of hunters can show good birds per day average when they come up here from Cali to club hunt a few days. Ratio is bad to look at because one might hunt 50 days and show 5 birds per day average and the other hunts one day and shows 11 birds per day average. Then take those two hunters and now they average 8 birds per day. See how skewed up this is getting now? The one who hunted one day added 3 birds per day to guy that hunted 50 days.
I don't think your math is correct. I believe the guy who hunted 50 days killed 250 birds (5 per hunter day). The guy that killed 11 in one day would be pooled with the 50 hunter day. That equals 261 in 51 hunter days raising the average from 5 to 5.11.
So your saying the guy who hunted 1 day and bagged 11 birds does not have an 11 bird per day average? Survey wants your days and ducks bagged which could give the average for each hunter then those numbers could be computed together. My point is statistics can be very misleading and the math can be done correct.
