5 level grayscale is like 10x10 sprites. it wastes opportunity. the way you
achieve 7 level grayscale is by having 3 video mem areas which are swapped
back and forth. you view one of them 4/7 of the time, another 2/7 of the
time, and the last 1/7 of the time. thus, each plane corresponds to a
different darkness level.
as for 5 level grayscale, not sure how you'd do that, but you couldn't do it
with less than 3 video mem areas, and you'd end up just having different
planes have the same darkness level, which is very pointless.
in conclusion, there is no point :)
