aa6fec66 added a check to reject modes with shorts longer than
 3.33 ms (less than 300 per second).
However, it only rejected modes which could not be split at all.
This expands the check to also reject modes which, even after
 splitting the maximum amount, still do not have shorts less than
 3.33 ms.
