Joe,
The vintage Oncore VP used a 9.54 MHz clock (which is why its sawtooth is about +/- 52 ns).
Stephan is using the newer M12+T (~40 MHz clock, which is why its sawtooth is about +/- 13 ns).
A 100.0 ns offset is more likely something to do with 10.00 MHz, which is why I suspect connections and settings of the 53131A counter.
