It sort of looks more like an unlocked OCXO than a magic frequency.
Measure phase instead of frequency; see how the phase drifts over time.
Also check if the magic frequency varies or drifts over time.
See if the offset is constant in spite of a one hour power cycle of either

One clock run fast
and one clock doesn't run at all.
Average that out, and you're pretty OK I guess :P
