Bundle scoring takes into account BASEFEE mechanisms to calculate miner's revenue from bundles.

Here is the formal definition of scoring functions:

v0.1

$$s_{v0.1} = \frac{\Delta_{coinbase} + \sum_{T\in U}g_Tp_T}{\sum_{T\in U}g_T}$$

v0.2-pre

$$s_{v0.2-pre} = \frac{\Delta_{coinbase}}{\sum_{T\in U}g_T}$$

v0.2

$$s_{v0.2} = \frac{\Delta_{coinbase} + \sum_{T\in U}g_Tp_T - \sum_{T\in M \cap U}g_Tp_T}{\sum_{T\in U}g_T}$$

v0.3

$$s_{v0.3} = \frac{\Delta_{coinbase} + \sum_{T\in U}g_Tm_T - \sum_{T\in M \cap U}g_Tm_T}{\sum_{T\in U}g_T}$$

$s$: bundle $U$ score used to sort bundles.
$U$: ordered list of transactions $T$ in a bundle.
$M$: set of transactions $T$ in the mempool.
$g_{T}$: gas used by transaction $T$.
$p_{T}$: gas price of transaction $T$.
$c_{T}$: fee cap per gas of transaction $T$.
$\delta_T$: priority fee per gas of transaction $T$.
$e_{T}$: effective fee per gas of transaction $T$ equal $\min$($c_{T}$, BASEFEE + $\delta_T$).
$m_{T}$: miner fee per gas of transaction $T$ equal $e_{T}$ - BASEFEE.
$\Delta_{coinbase}$: coinbase difference from direct payment.
