Hi folks,
While looking up the Cult Classic site address for Bill I wandered
over to the "Beating the 50 lines per mm Resolution Limit" site that
was/is hosted by the same author. On that site was a copy of an
interesting Email from Erwin Puts. It's a short Email with lots of
generalities but I think that it may help to bring a better focus on
the variables that more commonly affect the sharpness of our photos.
If you're interested in reading the whole article it can be found here:

degradation by a filter: good quality--> 2%, not good quality-->10%.
degradation by handholding below 1/125: 50%
degradation by (slight) defocus: 30 - 80%
