With a 525 cam it won't be much of a sleeper. Those cams sound damn good

So true. I've found cams to be off by 4*. Perhaps it was chain stretch, but you never know.

Is the built-in advance an attempt to compensate for chain stretch?

Nope. It's built in assuming everything is as it should be.

Always wondered. Since it seems they stretch quick and then stay that way a long time.
