This looks like a step in the right direction.

The "correct" allan plot will have a clearly visible horizontal
segment somewhere in the 100-10000 second range (depending on OCXO quality).

This is where the GPS long-term stability "takes over" from the OCXO's
better short-term stability.

Never attribute to malice what can adequately be explained by incompetence.
