I think that this focusing thing must vary between individuals, since so
many people have commented on how the 2-4 image "snaps" into focus, and my
experience was just the opposite.
BTW, I have both myopia and astigmatism, but wearing glasses (as I always
do) my corrected vision is excellent. My major problem is that I can't see
the whole screen, but that is another rant altogether. . .
I have always found the OM1 viewfinder to be relatively bright, except with
slower lenses (f4), so I guess I can continue to use the 1-series screens
without feeling too bad about what I am missing.

I find the point of focus with my 2-4 to be quite precise and easy to
judge. There is no region of vagueness that I have noticed. I
wonder whether eye sight is an issue here. Mine is not good so I
wear my glasses when looking through the viewfinder. I used to use a
dioptre correction lens on the viewfinder but a sizeable component of
my problem is astigmatism and dioptre correction lenses do not
correct for this. When I was using dioptre correction lenses I did
have a problem judging the correct point of focus as you describe -
using a 1-13 screen.
I know I am much better at focusing than I used to be, given the
brighter image provided by the 2-4 and the use of my glasses.
I would never dream of switching back to a 1-13.
I suppose there must be considerable individual variation involved
and it is not as simple as just saying that focusing screen x has y
characteristics which everyone will experience.
