| The math is really closer to a 70% difference:

Er, sorry, I was comparing ROM 7 & 8 versions of the Seagate. I get 431k/sec,
and 550k/sec is what the Seagate ROM 7 will do at 1:1. So, that's... 22%
difference between ROM versions.

Well, the ROM 8 does format 1:1, and an ST can read it, though it's doggo-slow.
The optimum interleave for any computer/controller/disc combination is
not always 1:1!
