Does TWISTER.PRG, published in this quarter's STart, work?  [Background: the
program formats floppies such that each track has its sector numbers offset
by two from the previous track, so that double reads of a single track caused
by seek and settle times are eliminated].  It sure sounds like it should work,
but I don't notice any difference at all!

I "twisted" one disk and formatted (extended) another, then copied the same
files (about 220K) to each; then I copied each to an extended formatted disk.
The results, plus or minus any irregularities caused by my timing method (a
Casio stopwatch), are identical.

The extended formatting program, from one of the magazines, sticks an extra
sector (up to 10 from 9) on each track, as does TWISTER; but it doesn't do
anything with the sectors.

Any help, as always, is appreciated.  One quick note:  throughout the article,
Dave Small (he and Dan Moore wrote the programs) refers to TWISTER with a TOS
extension, while the disk has a squeezed PRG file.

Thanks.
