I looked at it briefly.

Once you get to the loading screen, it does an M-W to store in various zp variables:

>8:0200 4d 2d 57 06 00 02 10 10 00 00 00 00 M-W.........
>8:0200 4d 2d 57 00 00 01 b0 10 00 00 00 00 M-W.........
>8:0200 4d 2d 57 0c 00 02 10 11 00 00 00 00 M-W.........

It then gets some data from a block:
>8:0200 42 2d 45 3a 37 20 34 20 33 20 31 30 B-E:7 4 3 10
>8:0200 42 2d 50 20 37 20 30 00 00 00 00 00 B-P 7 0.....

Here's the protection code. Just set a "break 300" in the drive monitor to see it. First breakpoint is the fastloader.

After running the check, it looks like this:

Anyway, it doesn't look like sync-counting to me. It looks like track alignment (fat track) between tracks 19 and 19.5. So you may be able to specify some options to nibwrite to recreate this sequence. Pete will know.

I did not spend much time (10 minutes) on the above so it may be inaccurate.
