| The current parameterization of [EIP-1559](./eip-1559.md) creates a large separation between Ethereum’s average computational load and its worst case computational load. The gas utilization target is defined as 50% of the gas limit, currently 18M gas and 36M gas respectively. This relationship amplifies the worst case load to always be at least twice as large as the average load. This forces the network to accommodate burstier loads and overprovision by an extra factor of two. | ||

| Closing the gap between the average case and worst case will improve the efficiency, scalability, safety of the network. |

Minor nitpick, I think this reads a bit better though

Two definitions for slope when gas_used_old = gas_target

| Increasing the gas target from 50% to 75% would have the same effect on mean throughput as raising the gas limit from 36M to 54M. However, the gas target approach is much safer against DoS attacks because it does not increase the size of the worst case computational load. | ||

| It would be desirable to target an even higher level of utilization than 75%. However, [EIP-1559](./eip-1559.md) requires that utilization must be able to freely move above and below the gas target, in order for utilization to be a useful indicator of demand. Putting the target near 100% makes it difficult to use utilization as an indicator of demand. |

Could you quantify what 'near' is, is 75% not near?

| This proposal does not increase the worst case load for node clients. This allows the network to scale more safely against the threat of DoS attacks. |

No mention of state and history growth? Could reference state and history expiry as possible solutions. I think more should be added to this section as it is really the main concern of this EIP.

This proposal changes the gas utilization target from 50% to 75%. This will increase mean network throughput without increasing the worst case resource utilization for Denial of Service (DoS) attacks.
