I had thought that perhaps the simplest p-MathML markup would not be
sufficient to disambiguate some cases, though it has worked for me so
far.

MathType markup is very close to Formulator, but it seems to me that it
declares style information a bit more often than is needed. I was
wondering if the current style is in response to specific situations
where you found it necessary.

I wish I understood the design philosphy behind MathMagic. Besides the
abundance of style information, there is <semantics>, which seems to
cause problems with some display engines. By the way, I have also never
been able to use the LaTeX output of MathMagic. Here is a comparison of
this same equation from MathType and MathMagic.

MathType
--------
${\hat G^{(T)}} = \frac{1}{T}\sum\limits_{t = m + 1}^T {{\pi ^t}}$

MathMagic
---------
${\hat{G}}^{\mathrm{(}T\mathrm{)}}\mathrm{{=}}\frac{1}{T}\mathop{\sum}\limits_{{t}\mathrm{{=}}{m}\mathrm{{+}}{1}}\limits^{T}{{\mathit{\pi}}^{t}}$
