Upgradeable gas cost overhead?

[abcoathup]

Hi @Met,

Welcome to the community

Thanks for the feedback, I have created issue https://github.com/OpenZeppelin/docs.openzeppelin.com/issues/241 for this.

As for the actual overhead, pre-Istanbul price changes the following test was done:

Gas overhead for proxied function call

Say, have you done any estimates on gas overhead for proxied function call compared to call directly to the corresponding function in the logic contract? If so is there any variance in or dependency of the overhead to be aware of when developing smart contracts with ZeppelinOS?
