ok, so you are basing your numbers on a single stand of trees... got it...
I guess, part of my point was, why (theoretically) does "lack of care" get factored in? it shouldn't get factored into TATF #'s... because TATF should be ontop of things and make SURE that the trees receive optimal care. now, according to the trees i have seen, the trees have received anything but optimal care.
if you are factoring lack of care from a single stand of trees, I think its a very narrow sampling to come up with any particular # ... I'm willing to bet that if owners get 5-10 really nice trees at the end of 25 years, ... out of original 100.... I'll be surprised
the lack of diameter on the trees I have seen doesn't bother me so much... because the trees WILL grow ...albeit slower than some others. what bothers me is the "lack of care" which I hope TATF hasn't assumed will happen.... though in actuality, is happening.
