Be careful with your calculations. Each bip 39 word adds 11 bits of entropy so 7 words would add 77 bits.
If you were using the EFF long diceware wordlist... 7 words is ~90bits. And 8 words is over 100 iirc. Even a small increase in entropy is an exponential increase in security so more is better.
Ah, thanks very much for that clarification. That definitely makes a difference.
I seem to remember some website where there was a table of how much security X bits of entropy gave you. Do you happen to know a good one?
For instance, a 6 word BIP 39 seed phrase gives you X bits of entropy and it would take a supercomputer X amount of time to crack. A 12 word BIP 39 seed phrase would give you Y bits of entropy, and would take X amount of time to crack.
