Still on the TODO.  Preg Calculator as far as I know has the same problem.
The "GnuMed About" window I made is okay... so the solution is at hand.
I think the fix requires understanding the code in the plugin base class.

Done. ***

TODO... will require some thinking.

The code needs some clean-up.  I added comments about where... will look
into this over the next few days -- unless someone beats me to it.

*** There is a little quirk in the calculation that is result of rounding.
if self.height==168 and self.mass==86
        self.txtbmi = 30.5
        self.newbmi = 30   <-- LOOKS WRONG (when compared w/ self.txtbmi)
        true BMI = 30.470521541950113 <-- What appears to be
                                          an error is a result of rounding!
There are a few comments regarding this in the code.
