this is a completely pointless statement.

please provide _proof_, i.e. explicit test examples
that show the hydrogen bond calculation does not work
as documented. just claiming, that you don't get different
numbers with different programs, doesn't mean zip.
there are several ways to define what a hydrogen bond
is and there are different ways to sum them up.
how do we know that you didn't mess up?

using a fudge factor is a _very bad_ approach. either
VMD does the correct calculation or not. a fudge factor
doesn't make a bad calculation correct.
