Suspiciously large gas overhead

I am testing this repo out and I am observing around 2.8K gas overhead (difference between calling logic contract directly vs via proxy).

This is significantly larger than the numbers below reported here https://forum.openzeppelin.com/t/a-more-gas-efficient-upgradeable-proxy-by-not-using-storage/4111

Proxy	Gas cost	Gas overhead
OpenZeppelin Transparent	29815	2770
Dharma Beacon	29752	2707
EIP-1882 UUPS	28679	1634
Storageless Beacon	28629	1584

I am wondering if there is something that I did wrong.

My compiler setting:

Solc 0.8.17
via_ir = true
optimizer = true
optimizer_runs = 2000

Can other users share their overhead number ?

Thanks

Any way to recover ether sent from proxy to CPO contract after self-destruct ?

I have called self-destruct on a proxy contract. It sends all remaining ether balance to CPO and now I am having trouble retrieving it from CPO.

That is my mistake... as I should either extend the CPO with a withdraw function or withdraw all ether from proxy before calling self-destruct

Anything I can do to recover the ether sent to CPO at this point ?
