My apologies for moving your post, and then failing to upgrade your membership so you could post here.

Regarding your question, it seems like you've gotten an reasonable answer to your question from not one, but two, local inspectors who've actually seen the pool. Of course, the only guarantee in life is that it ends in death, but it seems like the most reasonable thing is to go with the odds that your inspectors are correct.

I don't see any way that we could do better here: shell condition is never certain, but it's REALLY uncertain when those offering opinions haven't even actually see it!

Good luck
