tu80 problem

[Peter Swain]

One of our customers has reported similar problem with TU80s,
2200' being about the right figure for dump.
My guess is that the transitions to/from screaming mode write extended gaps.
>From memory, the standard IRG is .5", but an EIRG of up to 6"(??) is defined
for use in (say) skipping flakey tape patches by moving the blocks around past
the grotty bits.
Now I think about it, the Dump manual (or the code) admits the *assumption* of
.5" gaps.
