Summary: Format+ already reads at theoretical maximum speed

[]

There is no need to "twist" disks using the "dead sector" format ("format+")
since they already read at the maximum possible speed (one track per
revolution) (i.e. 5 per second) (that's single sided).

From some postings I now gather that it works (or is necessary) due to a bug
in the 1772 chip.  Is that right?  Is there/will there be a fixed version of
the chip?  Why do people design computers with chips with known bugs?
