Sounds like the problem is when you

loop through the view model updating each of the percentage rates to match

If so, then one answer for IE is to yield to the browser by using a timeout(0) call. When your JS resumes after the timeout, do the next iteration of the loop, then another timeout.

When I've done this, I only do the timeouts if I've sniffed that it is an IE browser. Otherwise, not needed.
