How can I calculate the total gas used by calldata for a particular block?

evm.codes has a wonderful about the EVM section about how gas is calculated. The way calldata gas is calculated is quite simple:
Deploying a contract with raw opcodes?

very interesting question - I checked this using evm.codes and the answer is yes: one thing to note is that simply fallback still has to check for whether the sender has sent eth, but a payable fallback truly has no switch case before it.

the ADD opcode is not concatenation, it is arithmetic addition. According to evm.codes, the fourth argument to delegatecall is the bytesize to copy from the memory (size of the calldata) - so adding the msg.sig (as a number) to the size of the calldata doesn't make sense
