Be careful not to insert an adjustment after a block that is split over 
two pages.

A more useful (from a user perspective, I do not know about the coding) 
solution would be a command to snap to the nearest grid line (up or 
down, half or whole step).

But both your count and my \snapto suffer from a common problem. Both 
are likely to leave different amounts of space before and after the 
block. A more evenly balanced approach is to compute the height of the 
block plus the vertical space by which it should be set off plus the 
vertical space needed to reach a grid-line or half-grid and, if the 
block stays on the page, split the difference top and bottom. If the 
block does not stay on the page, some portion with the top offset must 
be calculated and placed on the page if it otherwise meets widow/orphan 
tests.
