Since Dune has all the data in one place you can also check more general metrics.

You can easily assemble the data on average gas spent per tx, gas limit, gas spent in total in a block etc. using Dune.
Data on gas spent and similar metrics can also be relevant to certain protocols, so do keep this in mind.
