Yes, he replied with the following link:
http://www.oreillynet.com/pub/a/network/2002/11/27/bioconf.html

This page provides explanation and algorithm. The point is that this
calculation has to be done on the whole table, not on addition of a new taxon.
Thus this will bvery penalizing if eqch time we add a taxon, we force the
recalculation. Better let the batch doing so and default the values to NULL (or
-1 if not NULL, I did not check).

What do you think?
