Oh I agree and I mentioned that I do it too, my point was that 55 is not necessarily "unsafe" and in fact safer, in certain situations. Personally I'm over the fence at 60ish most of the time.
I gotcha now, thats about what I shoot for. Short final at my home drome is right over trees, so I try to aim for 65 and be a bit high. Easier to slow a 172 down on a dime than the T310.
