The reason 12 mm is the standard is because 10 mm is the standard dip. 
This is true for most pianos except those that have geometry problems or
improperly bored hammers.

Sharps are measured at the highest point perpendicular to the surface of
the natural, usually at the front upper edge.

12 mm minus 10 mm leaves 2 mm which is the "best" position above the
natural when a sharp is fully depressed.

Level the sharps to match the level of the naturals (unless those awful
.095" garbage (take it off)) then the dip is set so it exactly matches
the "after touch" of the neighboring naturals.  That is the one and only
bestest way to set dip on sharps.

Use your sense of TOUCH.  After all, touch is the way a piano is judged
by players.  Hopefully.
