Re: How do I identify the valid checksums for bip39 if I generate 11/12 of the word?
CSPRNG is better than your hand.
My hand is a lot easier to verify than the random number generator inside a piece of hardware.Quote
1. see that you flipped '1' too many times and decide to write a lie on paper that you flipped '0' somewhere in the middle, because it seems more random.
2. the opposite of (1)
3. get bored in the middle of the process and decide to add some bits by yourself.
That's just dumb 2. the opposite of (1)

It's possible to do this properly.I've seen discussions about bias in dice rolls or coin flips. For instance: Scientists Destroy Illusion That Coin Toss Flips Are 50–50, showing the coin "landed with the same side facing upward as before the toss 50.8 percent of the time". The article also shows ways to avoid this, but this small bias isn't something I'd worry about. No attacker is going to find out how you flipped a coin, and brute-force the entire 128 flips.
