I assume that should be good for a healthy engine.

WHERE is the leakage? My standard--not shared by the entire world--is that ANY leakage past the intake or exhaust valve(s) is unacceptable. ANY leakage into the cooling system is unacceptable. ANY leakage into an adjacent cylinder is unacceptable.
The ONLY acceptable leakage is past the rings, and then only within limits.
And without experience with known-good engines of the same bore size, or a Master Orifice, you have no idea if 8--10 percent leakage is acceptable. You can GUESS that it's acceptable. It is PROBABLY acceptable. But you don't know for sure.
And--as said--you still have seven more cylinders to test.

Agreed.

A failed torque converter stator one-way clutch could produce poor low-speed performance while not affecting higher-speed performance. But that doesn't really match your symptoms.
I suspect you still have "engine" issues, and you've not answered my questions about ignition timing and fuel mixture that I posted quite a while ago.
