To actually check it, probably yes.  Errors are magnified.  But to
actually do it, no.

Definitely not. Wildly misaligned slides can be quite acceptable
in a viewer, but still twist one's eyes off when projected.  I've also 
found that sometimes I've ended up with people with their waists cut off
when projecting -- but looked fine in a viewer (A Themelized one
no less).  I say this from experience..... :-(

Depends if one considers "seeing" the gauge show correctness
is considered an actual test of projection.

However, one still needs to check with a projector to judge
"exposure" -- unless one has a dimmed and "calibrated" projection-
simulation viewer.  Ones that look great in a viewer sometimes are
real disappointing when projected.  I speak from experience
again.  :-(
