Amazing progress honestly, very cool to see a report that feels custom made!
Awesome to see you using my math as well, which makes things easier to check

Using immutable on variables that are only set in the constructor and never after (2.1k gas per var)

14.7k

Pack structs by putting data types that can be packed together next to each other.(Total SLOTS saved: 6 ) ~ 6 * 2k = 12K gas saved

I think only 2 are valid, rest are memory values
4k

Rest is minor, prob 2k at most

20.7k

The result of a function call should be cached rather than re-calling the function
Around 200 gas (100+ from balance, rest is negligible)

Storage Pointer
25 times 40
1k

Avoid contract existence checks by using solidity version 0.8.10 or later
Invalid compiler is .17

Rest is minor, 200 gas I'd say

22100
