On top of this, the shafts from used M97 engine's do not show this tendency.
So basically, if you got an M96 with a shaft with run out, and it happened to be a single row engine, the odds were stacked against you being a happy camper.

Here is a hint of how to qualify a would-be M96 engine rebuilder: "Would you let me see the IMS runout test on my shaft?
And what about the other 6 items on the list of 7 supplied by Smallblock
My guess is that only well equipped and trained machinists would be able to do this test.The average engine rebuilder would not have the correct equipment ,nor even know what to look for.
The pragmatic suggestion is to use a new M97 shaft when rebuilding an old M96 ?How else do you buy an M96 shaft that is straight? Then you do not need such a fault-tolerant/expensive bearing ?Dang - I did not know this when I rebuilt mine - next time.....:-)
