Interleave refers to how many sectors (on the track) must be skipped
over by the read/write head between sector accesses.  The difference
in access time between the SE and Plus is a function of the disk's
rotation speed and the number of sectors per track.  It is not
dependent on the number of turns it has to make - sector accesses do
not require having to wait until the track makes a full turn to get to
the next sector to be accessed, only for the next one or two sectors
to pass (to get to the one you want).
