I've gone as high as 87 uS...but it went deep yellow in a few days and eventually dropped back to 30 uS.
PPM unknown, but well over 87.

25 to 30 uS is easy, but not generally very stable staying colorless...depends on the water mostly.

Yes, stirring will definitely mix up the ions. It will also severely limit
the maximum silver ion concentration you can achieve. So there may be a
severe contamination problem if you are measuring 15uS. But you don't care
what results you get, so I won't.
