[time-nuts] PICTIC II questions

On the schematic is a list of alternate XOs. For 50 MHz, the 1000 pf
cap is changed to 180 pf. This is stated to give 25 ps maximum
resolution. If this simple change is all that is required, I can
easily substitute the parts to obtain better resolution. Has anyone
made these changes and used a PICTIC II with a GPSDO and rubidium as
inputs? Is it good enough?
