If you're taking a residual baseline measurement by feeding the same signal to both the start and stop inputs, then that looks OK.  But if you're measuring one OCXO against another, then it wouldn't be correct since it doesn't show an increase in instability at longer taus.  (If you like, send the .tim file to john at miles.io and I'll have a look at it.)
