Summary: LP: how long?

All this talk about long-persistence monitors leads me to wonder.  Does
anybody have some quantitative knowledge of the time constants
involved?  What is the 1/e decay time of "short" vs "long" persistance
phosphors?  I'm mainly interested in color monitor phosphors, I don't
care to know about 15 second green monochrome.  And what is needed to
kill most of worst-case perceptible flicker?  My uneducated guess is
maybe .05 to .1 second.  What I'm getting at is this: Is it *possible*
to have a "medium" persistance monitor that neither flickers much nor
smears much?
