Hi,
please have a look at this minimal example below:
you'll find three formulas (1), (4), (5)
What happen to (2)  and (3)?

.......
\starttext
\placeformula \startformula a+b=c \stopformula
\bTABLE[frame=on,align=right,width=fit,style={\switchtobodyfont[9pt]}]
\bTR
\bTD[width=35mm]
\placeformula
\startformula c-a=b
\stopformula
\eTD
\eTR
\eTABLE
\placeformula \startformula c-b=a \stopformula

It’s a bug in the formula numbering. Natural tables perform three runs on the table
content to calculate the cell size but formula etc. counters shouldn’t be increases
in the first two runs.
It's always hard to predict side effects (as we can have more data being 
involved; also. not incrementing will give the wrong number and 
therefore the wrong size calculations.  Something like the following can 
be used for testing:

\strc_formulas_handle_numbering
\let\strc_formulas_handle_sub_numbering_indeed\strc_formulas_handle_sub_numbering
\let\strc_formulas_handle_sub_number_indeed 
\strc_formulas_handle_sub_number

\def\strc_formulas_handle_numbering
   {\iftrialtypesetting
      \strc_counters_save\v!formula
      \strc_formulas_handle_numbering_indeed
      \strc_counters_restore\v!formula
    \else
      \strc_formulas_handle_numbering_indeed
    \fi}

    \else
      \strc_formulas_handle_sub_numbering
    \fi}

\def\strc_formulas_handle_sub_number % sub formulas
   {\iftrialtypesetting

      \strc_formulas_handle_sub_number_indeed
