RE: [TCML] BPS Testing

["Lau, Gary" <Gary.Lau@xxxxxx>]

While missing 3 laminations shouldn't make a big difference if everything else is the same, there is the possibility that the reassembled components did not go back together perfectly tightly, and this would have the net effect of fewer laminations.
