it's worse than you think -- on some machine/display combinations,
the effect speed is ignored entirely!  
the effects are not shown on IIcx's with color screens (for example) 
(at least, not with 6.0.3 and whichever Hypercard was current then).

a friend had loaned me a stack he'd written (John Cramer's Isotope
table) -- and i suggested that sideways wipes would be appropriate.
and he said they were there!  true enough, i loaded in onto an SE
and there they were (but the whole stack was a lot slower :-()

so a little digging in the Hypercard release notes did indeed documnet
that the Apple color card did not support the visual effects.  hence
their speed had no meaning.
