Have another question about a leak down results. How does this explanation sound for a poor leak down result?

No 2 cylinder has 50% on leak down and all cylinders borescoped look fine so Porsche mechanic it is a stuck ring. Under normal driving, the car doesn't miss and accelerates like it should which all favor the diagnosis of the stuck ring. It does not burn more than normal oil consumption per Porsche factory limits. I had him change the oil and plan is to drive it a few hundred miles and repeat compression leak down test.

I guess this probably means that engine job is eminent?
