There is a version 1.2 of spintest which is more accurate than
whatever the (unidentified) version was/is. It is also larger (over
3 kbytes) because a lot more verbiage is included explaining
interleave and interleave-testing.

I personally formatted a drive at 2:1 interleave, ran the earlier
spintest and was told it was a 3:1 interleave. Version 1.2 reported
the correct 2:1 interleave factor.

By the Way - spintest doesn't report the interleave factor for my
CDC Wren IV SCSI drive, but it does report the bytes transferred
per second: 1044,480 (!).
