One more quick question. When using a grid, I gather that I should wrap all floating content (tables & figures in my case) with \placeongrid to ensure \snaptogrid is being used. Does this also apply to formulae? i.e. should I be using:

\placeformula
\placeongrid{%
    \startformula
    ...
    \stopformula
   }

Thanks,
Randall
