Some interpret the actual wording and will report the 84 deer (as used in my example), whereas many others will look at this number and say bollocks and only report the six animals. From my personal experience you get about 30% of the hunters doing the 84 report, about 50% reporting the count as six, then 20% falsifying their report by reporting much higher numbers (the idea being that high numbers will keep the doe tags and additional tags going). The old data saying of “garbage in means garbage out” comes to mind. There is such massive variance in how the info is being reported that i don’t see how even “ a line of best fit” can be
established to make any legitimate trend comment. I’ll have dig through the dust archives out in the barn. I’m sure i have some abstracts copied on background of the ODM (Ontario Deer Model) input variability, validity using mail in hunter surveys for big game management decisions, etc
