Should we set an ideal number of reps for each country?

The main question for me here is:

How can we find out why Reps is considered as an achievable goal to proceed in the “volunteer Mozillian ladder”? I’ve heard this multiple times in the past few month and I’m sure we need to make sure to tell people that they can achieve a lot without being a Rep.

I think it’s quite hard to get feedback on this. Any ideas?
