I'd agree with that. The human component is the important
variable. Repeatability and detail is there for the getting

Take these examples

PIC + quad amp + 0805 R and C. Very small text under
the 'JC 3.11' is my note for the board size. It is just about
readable (if you know what it's supposed to read. FWIW
it says, mirrored, 1.85 x 2.65  4.70 6.74 @ 600 dpi)

Printout (0.1" pitch pads)

Result (a little out of focus, better looking in reality)

I read one person's account where he uses a hot-plate with a
weight to apply a known pressure for a known time. That's
something I'd like to investigate. My gauging of iron pressure
is fairly good and but I'd rather it be controlled, for a more
consistent Toner Squash Factor, which causes holes to shrink
and tracks to widen. That said, SOIC 0.05" pitch is quite
easily achievable
