9d8 works. It makes sense that it'll increase Str that extra point, I agree.
The question is, is it nastier than the CR 7 Black Pudding we based the stats on?
I'd say yes. It does have 10 attacks, after all, each with a damage roughly the same as a Black Pudding. It doesn't have a Black Pudding's special defences of Split or weapon-destroying Acid but its half-damage from slashing & piercing partly compensates.
So maybe CR 8 or 9?
That looks like it apart from its Challenge Rating, Max Advancement and the fluff.
CR 8 will work, and I'm fine with 49 HD at max. Are you just adding this to the end of the main silver slime entry? If so, it'd be good to put a news item up mentioning that we're still here. You could mention the corrected sentinel eidolon, too.

Don't we just have a common description and background section for all the silver slime life stages? I was going to check the CC for that, but it seems to be down. Is Morrus working on it?
Ah, yes, in that case, what you have looks consistent with the rest. All done?
