📝 Original message:I like the simplicity of this approach. Demand driven response.

Is there really a need to reduce the max block size at all? It is just a
maximum limit, not a required size for every block. If a seasonal
transaction surge bumps the max block size limit up a notch, what harm is
there in leaving the max block size limit at the "high water mark"
indefinitely, even though periods of decreased transaction volume?

I'd argue to remove the reduction step, making the max block size
calculation a monotonic increasing function. Cut the complexity in half.
