This is why I suggested a bimodal result.  The hole in the middle is  
the 1%'ers removed.  Re pistons, I  thought they all were undersized,  
and the rings adjusted for any variation.

bc, knows the mass (moment of I, approximately) is adjusted carefully  
by the mechanic's filing the crook at the big end of the more massive  
ones.
