Variant 1:

\newdimen\baseoffset \baseoffset=28px

\setlayer[…][voffset=4\nuggetnumber]{…}

Variant 2:

\def\nuggetnumber{4}

\setlayer[…][voffset=\dimexpr28px*\nuggetnumber\relax]{…}

Variant 3 (what i suggest):

\definemeasure[baseoffset][28px]
\definemeasure[verticaloffset][\dimexpr\measure{baseoffset}*4\relax] % replace “4” with your own factor

\setlayer[…][voffset=\measure{verticaloffset}]{…}
