Hello Pablo,

Thank you very much for the help. The penalty of \blank indeed brings the
solution closer and it does format the previous example correctly.

However, when I went back to the original document, neither
[before={\blank[preference, big]}] nor [after={\blank[samepage, big]}] nor
both worked. I trimmed it into the following example which behaves the same:

    \starttext
    \showframe
    \dorecurse{50}{a }
    \startsection[title=spec][before={\blank[preference,big]},
after={\blank[samepage,big]}]
    \startxtable
    \startxrow
    \startxcell[ny=30]a\stopxcell\startxcell 1\stopxcell
    \stopxrow
    \dorecurse{29}{\startxrow\startxcell 2\stopxcell\stopxrow}
    \stopxtable
    \stoptext

Do you have an idea on how this could also be formatted correctly or how
one could inspect and debug the penalty?

Thanks again!

Sylvain
