I'm a noob but i'm wondering, what's the math behind the new deflationary measures? Is it public? Will it ever get to 1?
Yea, it's all public. Not sure what you mean by "Will it get to 1?"
Miners used to get the reward for processing/mining the next block on the blockchain plus the transaction fee from the user that is sending either ETH, tokens or interacting with a smart contract.
Reward = 2 ETH block reward + transaction fees.
Now, after EIP 1559, the transaction fee is burnt so the miner still gets 2 ETH for the block reward/mining the block but if all the transactions included in that block is more than 2 ETH then more ETH is burnt than was generated by a new block so it's deflationary.
This will only happen when there's lot of actvity on the network like yesterday for example.
Right now, with low activity you can see that's the amount burnt is not more than 2 ETH.
Also, if you're wondering why the rewards are more than 2 ETH, it's because users can tip miners when making a transaction to make it faster by including it in the next available block.
Basically the same as before where you can increase the gas limit to make your transactions faster.
