I have a wall I use for print evaluation. It has a large magnetic white
board, and strip magnets on it, used to hold the prints. I put up prints
side by side and evaluate them. My largest print size is 17x22 from my
3000. I can see differences from "standard viewing distances" that have
convinced me that 180+ is the minimum resolution that is acceptable to me
for the type of work I do, if not 240+ preferred. 100 is vastly degraded.

Where has this been agreed upon? I'm not doubting it, but I never heard
that. I also would say that probably doesn't hold true for (especially B&W)
darkroom prints with decent negatives and decent enlarging lense.

In order for me to print at 100dpi (without decimating the data), I would
have to make a VERY VERY large print. For a 2 1/4, I scan at 2540...and
that gives me a 24x24 print at 240. I'd be over 50" x 50" if I was to print
Point is, whether 100ppi looks "good" at all VASTLY depends on print size.
Certainly 100ppi will look GREAT if the print is the size of a billboard,
but for a 13x19, it looks poor, IMO.
