I think the discrepancy relates to the fact that the crank turns twice for every one turn of the camshaft.

So the FSM is referring to degrees at the camshaft and the parts suppliers are referring to the degrees at the crank, which is where people measure stretch. The FSM values are twice the parts suppliers'.

The key you need is the difference between the reading and 11 ATDC. It looks like you have about 2 degrees of stretch.
