The number before the asterisk is a multiplier to repeat the value n times.

The value for small is font dependent which results with the default 
font and size. When you check the value you can see it is slightly 
smaller than 1mm which means when you use \blank[1mm] your manual 
setting is too large.

(Of course, at least once, it was there where I had already looked but I didn't understand enough to realize it!)  I even gave searching the mailing list archives a shot.
