That seems extremely odd.  I'd really like a better explanation before
I accepted it as fact.

If error recovery is taking a significant amount of time, amortized
across a workload, then something seems wrong.  Worst case, sure, but
not average case.

If it is just normal final adjustment on seeking, that should show up
in the specifications and I don't think that it does (but I haven't
checked).

Do you know more?
