Hi pablo, regaring 1) TeX assumes that each character is a variable on

I don’t know whether this is a bug.
Itemize uses the mixed columns when you enable columns with enabled grid
snapping
as default setting. To get rid of the extra line you can either disable
the grid setting
for itemize with
\setupitemize[grid=no]
or you replace the mixed columns mechanism with a simpler column
mechanism which
doesn't produce an extra line, to do this add this at the begin of your
document
\enableexperiments[itemize.columns]

Now it’s clear to me that math and text modes are different in practice.

Re: [NTG-context] basic issues with formulas
Hi Pablo,
You may use \text in math formulas as in:
\startitemize[packed]
\item Valor actual neto: $\text{beneficios} - \text{costes}$.
\item Beneficio por euro: $\frac{\text{beneficios}}{\text{costes}}$.
\item Beneficio obtenido el primer año.
\stopitemize
