Well... the theoretical improvement is tiny (I think 5% or so) and I bet nobody saw any difference.
The trick is to lower timer A as much as you can (since increasing that will increase the jello effect).
Also, I'm under impression that slower shutter speeds have less jello effect, the jello at 3fps is very obvious at very fast shutter speeds, but not so at slower ones. But that is probably true only at 3fps, not at 24.
