Thank you for your detailed response. I wanted to deal with
the language part separately from the technical in case
anyone wants to tune out one part or the other.

http://encarta.msn.com/dictionary_/interpolate.html
I'm sure different people prefer different online English
dictionaries. In this one, they both seem perfectly fitting
choices to describe counter-based estimation of system time
that underneath sawtooths.
Perhaps you don't know B. I know B. It's coming in a few
milliseconds to a Windows clock underneath my palms. ;)
But whether I know B or not, if you take the definitions
above rather than yours, either word fits perfectly.
Cheers,
Dave Hart
