 At any block we don't want the gas update factor (whether pushing gas up or down) to exceed ~1.125. This is essentially achieved in [EIP-4844](./eip-4844.md) by having an appropriate `BLOB_BASE_FEE_UPDATE_FRACTION` to divide `excess_blob_gas` accumulator while exponetiating it
 
-Since the target from CL could theoratically change block to block, we need to normalize excess gas accumulation because the update fraction is actually directly based on both the target and max (max value `excess_blob_gas` can jump by in a block).
+Since the target from CL could theoretically change block to block, we need to normalize excess gas accumulation because the update fraction is actually directly based on both the target and max (max value `excess_blob_gas` can jump by in a block).
 
 We propose to "normalize" the gas diffs every block against its target/max and then accumulate in `excess_blob_gas` so that we accumulate normalized `excess_blob_gas` every block and can use a constant normalized update fraction in our fee calculations.
