Diamond League Player. Someone please answer this math question.

It's obviously not linear so asking for the average is dumb. You can also level up obtaining no gold but the passive gold everyone gets if you don't last hit anything but are close enough for experience.

It's a poor question to ask, what are you trying to accomplish with this question?

That is ALOT of math to do. Could you tell us why before we try calculating that?

all the gold Kappa

I suppose you could calculate the gold value of the base stats but there is no real answer to the question.

For example, the enemy laner dinging level 2 or level 6 before you is much, much more of an advantage than the 200g (or whatever) of stats would lead you to believe

There are 130+ champions, do you want the mean among all of them or just a restrict portion of champions? Also you want it champion wise or environment wise?

It used to be ~800-1200 before Riot buffed every champion's bases and nerfed scaling a few seasons ago.
