This contract gives you ability to stake your NFT(s) and earn reward tokens (an imagined ERC20 token) in return.
Any owner of the NFT collection (see the contracts folder, MyNFT.sol) can stake their NFT into the Controller (Controller.sol) contract by sending their NFT to it. Then, each 24 hours, they receive 10 ERC20 Tokens (MyToken.sol) per staked NFT. If they withdraw, they forego the reward. The rewards only occur in 24-hour intervals. No partial rewards are given. So only after the delta time > 24 hours do they receive 10 tokens. If greater than 48 hours, they receive 20 tokens, and so on. They can claim multiple times, but only receive whatever they are entitled to between the last call and now.Deployments took place on Goerli.

Upgraded contract: 0x6B16dd3D4439feFA3e64cc98b907B5F3630C8b40
Now, before verifying it, etherscan showed this:
Implementation contract is now on 0x065f88606812529eb8b144bb0c16c88e8c9fdfab but NOT verified. Please request for the new implementation contract to be verified.
So we need to verify the upgraded NFT contract:

Now verify this on etherscan by seeing the "write as proxy." Indeed I saw the new updated function:

Upgrade the NFT contract to the God Mode version:

We see that:
- createNewERC20 takes up an average of 1,608,856 gas.
- createNewERC20WithClone using the Clones pattern takes up an average of 270,561 gas.
Note that each was called 4 times in total.
Thus, using the Clones pattern in this specific setting is ~16.8% of the vanilla creation approach (and thus >80% more gas efficient on contract creation).
