What Gerry said, ground 10 thousandths under standard. Or it could mean a perfect 10 out of 10 crank, all the right curves, looks good in a bikini and all that.

No performance effect. It just means that the crank was worn enough that it required machining to smooth and true the journals. When you rebuild an engine it is usually done. Future rebuilds may require it as well. You can turn a crank as much as 30 thou. Bearings have to match it as well and are sold in standard sizes of 10, 20 and 30 under.
