>From discussions on the list last week "I'd understood"* that
the tape length and I assume** by extension the filemark size
are used only to estimate tape capacity and determine what needs
to be bumped or if a level zero could be advanced.

What is the speed value used for ?






* Note, phrase "I'd understood" has no confirmed relevance to reality
  and may not be worth the electrons it was written with.
