I'd guess that add/delete of low values and of high values would leave behing 
different structures, but that the differences wouldn't affect performance 
significantly; certainly not as much as one ABEND due to failure to prime.

As for REPRO, I'd like to know that too.

Is the result identical whether the added/deleted record has key high-values, 
low-values, or something
in between?

And I'll repeat my question, what is the result of REPROing a properly 
initialized
but currently empty KSDS?
