Vertically aligning text in a field

Is there a definitive calculation that correctly sets the position of text vertically in a field?
I am using LC 6.7.
I have come across a few ideas like the one below that all appear to use an arbitrary offset to the margins, is there a method to calculate this accurately?
put the effective textSize of fld id tID into tTextSize
-- put round (((tTextSize - 22) * 1/3)) into tOffset
put round (((tTextSize - 24) * 1/3)) into tOffset
put the formattedheight of char 1 to - 1 of fld id tID into tFormattedHeight
put round((the height of fld id tID - tFormattedHeight) / 2) into tVerticalMargins
put tVerticalMargins - tOffset into tTopMargin
put tVerticalMargins + tOffset into tBottomMargin
set the margins of fld id tID to 8,tTopMargin,8,tBottomMargin
All the best
