If you're referring to the list of 100 or so Brightest on Celestrak, I 
set that up to include satellites that are usually easy to see for the 
average observer. I set a mag limit of about 3.8 for that. This is 
determined by actual observation.

I think other lists use theoretical predictions based on assumed size.
I don't know what their limits are.
