I would RELY on what the limits are.
I remember back in the day when we were adding more graphic channels to Macromedia Director and we went from 64 to simply what the computer running our implementation had the RAM and processor power to handle.
We set it higher (I forget what) but it was limited by the machine's capabilities. That way we could up the max amount as machines gained capability.
So, it might be able to support more, but not consistently across every machine/device.
That's my guess.
