Interesting idea. I'd speculate that the accuracy problem where the counter failed to see some pulses is perhaps a synchronization problem. If the pulse-counting method worked by generating a variable number of pulses at 240kHz then they should always be visible to the counter as long as that's within it's range. But if the gate period of the counter didn't coincide with the gating of the pulses at the generator, you would get variable results. And there's no obvious way to make them synchronise without stop/start signals.
