I think live2farm is asking a quantitative question, not a qualitative one. You must be analytical like me.
I have not paid much attantion to "hunter days" to see how sucessful a unit is as most people aren't looking to punch a tag on day one if it is a quality unit anyway. Now on a doe hunt, maybe. I do take into consideration how hard a unit is to draw, as I figure in a unit like 39 early deer with about 30% draw odds, folks are likely to kill the first deer over 20" they see, while in units 40/44/45 they may well pass up a small forked 27" buck the first day. The fact is in those low odds units, say under 8%, many people may eat that tag, despite having opportunities at 160-170 bucks, while that would NOT happen in 39.
Given all that I simply take the success % for what it is. In low odds units I also look at %4pts.
I have some rediculous spread sheets and formulas that I have looked at over the past few years. Bottom line is that the only significant conclusion is that, it gets harder every year. More applicants in good hunts, and more hunters in OTC areas. NO BREAK.
Qualitatively, yes the harder you work no matter what you take or pass on, the sweeter the reward.
