With 10k I got the pause down to 9uS code but the circuit stopped speeding up after 16uS. I think it just can't read any more pulses after a certain speed or the basic language is not allowing anything faster. 5k resistors don't change anything.

I just commented out the pauseus commands and now have a dollar store watch (the test circuit) that counts out a minute every 2 seconds.

Based on the speed of the watch, I should be getting ~600khz right now. I didn't think it would be able to count the pulses past about 100khz. I have no other way of generating faster pulses, so I'll overclock the pic to 30mhz next week and see what happens.
