At line 102:
Incorrect Formula For refund :
max fee - (base fee + tip)

Corrected Formula For refund:
(gas limit−gas used)×(maxfee−(base fee+tip))

Reason:
1.max fee - (base fee + tip) gives the per-unit refund, but the
actual refund depends on how much gas was unused.
2.gas unused = gas limit- gas used .

Hey @AvulaRamSwaroop, thanks for the suggestion.. I see where you're coming from, just not sure this is really necessary? I think the calculation that is there is simple enough to read (in "per-unit" terms) and it gets the point across that the excess is returned. Feel free to push back; small change so not a hill I would die on

Hi ,As a beginner I felt little confused for a While cause the line is stated as :

any gas not used in a transaction is returned to the user (i.e. max fee - (base fee + tip) is returned).

So I later came to known that ,this must be multiplied by gas unused units .

if it is per-unit terms then no need to modify it .

Thanks for your Time.

Hey @AvulaRamSwaroop, apologies for the delays... Yes, these are in per-unit terms. Going to close this out for now but appreciate the idea. If you'd like, feel free to open a separate suggestion to improve wording if you feel it's necessary ❤️
