Do you have sources for those numbers?

I know nr of physical qubits may also vary per methods, and there are 6+ methods out there. From my understanding, in the end it's about reliable logical qubits with sufficient retention.

Are the logical qubits all there is? Are the toffoli gates strictly an extra number or can you trade off one for the other to some extent? (Just wondering.)

I'm curious what method, configuration and such will prove most reliable.

Also, P2PKH already prevents early exposure. Right? So as long as an address is used only once, it is safe until the bitcoin transaction is created to spend the utxo. (So short window before confirmation that it's vulnerable. So essentially only a window for (near-)real-time attacks.

That's my understanding of the situation, at least.
