That was indeed too good to be true. A case of me misreading my own log
file format: the RMS error is 0.0287 of a sample period, which at 100ksps
corresponds to 0.287 microseconds, or 287 femtoseconds at signal
frequencies for a 10Hz/10MHz DMTD. (Multiply by 10, not divide by 10...).

My apologies,
