Thanks, Hans. That is very useful.
I also recompiled my textbook draft using the latest beta (2014.05.17),
and it works very well. I tried the topdistance and bottomdistance and
they are mostly working. To my eye, with topdistance=6pt, the {1\over2}
looks very good again.
However, the settings don't seem to affect fractions inside square
roots. Here's an example (the 20pt setting is to exaggerate the
possible effect), using 2014.05.17 beta.
\starttext
\placeformula\startformula
\dfrac{ag}{bcd}\quad{ag\over bcd}
\stopformula
\placeformula\startformula
\sqrt{1\over \dfrac{a}{bcd}}
\quad
\sqrt{\dfrac{1}{\dfrac{a}{bcd}}}
\stopformula
\setupmathfractions [topdistance=20pt]
\placeformula\startformula
\dfrac{ag}{bcd}\quad{ag\over bcd}
\stopformula
\placeformula\startformula
\sqrt{1\over \dfrac{a}{bcd}}
\quad
\sqrt{\dfrac{1}{\dfrac{a}{bcd}}}
\stopformula

The 3 and the 1 sit quite high above the division line, esp. in

The place okay without the \setupbodyfont[palatino], so maybe it is
something incorrect in the font parameters?
The fonts are (from 'pdffonts'):

keep in mind that a too small distance can give inconsistent output
Is there a way to adjust the spacing, or an alternative workaround?

Re: [NTG-context] numerator is too high in \frac{3}{4}, in palatino
I just compared MkII and MkIV in this respect, and the MkII fraction
looks more symmetric (more correct) than the MkIV version.
Here is the MkII code:
\usetypescript[palatino][ec]
\setupbodyfont[palatino]
\starttext
\startformula
{3\over4}\quad {1\over2}
\stopformula
\stoptext
I've attached (cropped) images to show the difference.
Another difference is in the fonts. For the MkII version, pdffonts gives
IVJLXF+TeXGyrePagella-RegularType 1Custom yes
yes no 4 0
IVJLXF+TeXGyrePagella-RegularType 1Custom yes
yes no 5 0
For the MkIV version, pdffonts shows a math font (maybe for the
thicker fractional bar):
EUEJAR+TeXGyrePagella-RegularCID Type 0C Identity-H yes
yes yes 18 0
UPBTGS+TeXGyrePagellaMath-RegularCID Type 0C Identity-H yes
yes yes 19 0
If you have suggestions for how to change, slightly, the numerator and
denominator placement when using alatino, let me know.
Maybe the entire problem is that the division line is thicker in
Palatino math than in the text font, and maybe sits below the math axis
(so it gets too close to the denominator)?
