 * **`Gamma`**: This determines whether you are additively increase or multiplicatively decreasing the learning rate based on the target and current block utilization. This must be a value that is between `[0, 1]`. For example, if `Gamma = 0.25`, then we multiplicatively decrease the learning rate if the average ratio of current block size to max block size over some window of blocks is within `(0.25, 0.75)` and additively increase it if outside that range.
 * **`MaxLearningRate`**: This is the maximum learning rate that can be applied to the base fee. This must be a value that is between `[0, 1]`.
 * **`MinLearningRate`**: This is the minimum learning rate that can be applied to the base fee. This must be a value that is between `[0, 1]`.
-* **`Delta`**: This is a trailing constant that is used to smooth the learning rate. In order to further converge the long term net gas usage and net gas goal, we introduce another integral term which tracks how much gas off from 0 gas we’re at. We add a constant c which basically forces the fee to slowly trend in some direction until this has gone to 0.

+* **`EnableTips`**: This is a boolean parameter that determines whether tips are allowed in the fee market. When set to `true`, users can include optional tips with their transactions, which are paid directly to the block proposer. This can incentivize faster transaction processing during periods of high network congestion. When set to `false`, the tip mechanism is disabled, and all fees are processed according to the base fee calculation.
 
 The calculation for the updated base fee for the next block is as follows:
