Well as for me I go to Chap 3 - 2 - 1 and I get around 3 to 6 Sealstones with 143 HP

You can check if it's good there for you.

It's true searching in latest chap is wasting your health, same with lower ones since it has low probability for sealstones to appear, I'd go for a mimimum of 3 HP cost to 10 cost max.

Depends on what are you luckier in, it's supossed to be that HP consumption is proportioned on the Sealstone probability, supossedly the more HP you consume the higher the chance of Sealstone but it doesn't really look that way... try Chap 3 to 6 if not try higher levels until you find the best one for you.
