There is no doubt: The average D/T-values of hides is much higher than for find. Just because those with low D/T values have more finds.
My finds have an average D=1.81 and T=1.83
For the hides I would estimate average D=2.1 and average T=2.9.
I have 480 hides, now, and
"301 (62.7%) hides were rated with Diff or Terr of 3 or greater "
I love caches in trees and mountain tops, but most of these have only one digit visits. Easy access caches have three digit visits. (Trondheim, Norway is not too densely populated...)
