Ah that's interesting. I think it partly depends on the drive you're writing with, too. As you say it's unpredictable, but a well-timed write splice should indeed work well. However I can't place arbitrary splices with Supercard Pro -- afaik that is always solely placed at the index mark. Hence my search for other tricks, and it took a good while of fiddling to find the one I describe in the OP.
Writing the same sector/sync twice is pretty cunning, I like that. I guess you need lots of cunning to produce these tricks via a standard IBM-format controller chip
It wouldn't work on the specific track I mentioned as the copy protection waits for the index pulse on each iteration.
