Don't think so.

IIRC the OP said the tubing diameter went from 4" down to 1".  If you
modeled in NEC with stepped-diameter correction to get an equivalent
uniform length and then took a percentage before changing back to
tapered, you might get there.  But if you can model in NEC, why not just
work out the change there?

And how accurate does it have to be?
