Not really, there are a whole variety of code limitations, at least in
SwishMax as far as like how many functions you can have per
sprite/scene. That's why I had to break it apart into 11 different
sprites. It also has to be broken up on the frame level (which is
most likely adversely affecting the speed) in order to get the save
progress meter to work. If there is some other way of doing I've
never seen it. I did a LOT of experimentation on it though and what I
got is the best I was able to find. Most of the other methods I tried
resulted in time outs, browser lockups and browser crashes.

What's slowing it down though isn't the calculation (really my method
doesn't really have any calculation so much), it's the IF statements,
which run so damn slow. CASE statements process a lot faster (as far
as I know) which is why it should have a significant impact on the
overall speed...but that's provided that the speed limitations aren't
a result of the frame level processing. I might try increasing the
frame rate of the SWF file and see what effect it has.

Yeah apparently no one else has either. Everyone keeps linking to
this one blog entry about it though and talking about how awesome it
is. I found one live example site that's supposedly using
it...although I'm not sure if they implemented it as well as they
could have because it's only about twice as fast as the method I'm
currently using, so that's still pretty slow.
