Hey,
My apologies for the response times, here is the information about license count.
Having 4 or 40 packages on the same system will only count once. If you are not using authenticated packages, we are using the user ID on the system as part of the calculation so if you use on a test VM a package as well under “randomuser123” and “bob”, you could count as twice despite being a single user.
A single developer can use it on up to 3 systems, as long as a user ID matches.
I hope you find this information useful
Best Regards
Ignacio
