Sorry for replying to you, rather than the original poster... I don't
have that post any more. :)

The issue is that this thing makes sense for solving ODEs, but is pretty
useless for the numeric integration. While numeric integration is a
special case of solving ODEs, the actual algorithms are completely
different... the main difference being that ODEs tend to be solved
stepwise, while functions get integrated in order that isn't even
necessarily sequential (Romberg algorithm is the primary culprit here).
