You mean out of twelve words right? So how much is limit for the twenty four word seed?

The same. If you are missing 4 words then there are 2048⁴ possible combinations, regardless of how many total words there.

speed-wise recovering a missing word in a 24-word mnemonic should have a slight edge over smaller number of words such as 12 because there is far less number of collisions in 8-bit checksum than there is in 4. Roll Eyes

Is actually valid... that is crazy. But if it was someone who just created a wallet, wouldn't they probably not think that much of it though... but it looks weird?

if someone did create such a mnemonic they should doubt the correctness of the RNG that their wallet is using because this type of distribution in the entropy is highly unlikely if the bits were generated randomly.

Well im surprised how someone can't just hit a 12 word seed then... I would thought it wouldn't take that much time to hit even one.

it could help if you stopped thinking about finding X number of words and think in terms of the entropy size these words represent. a 12-word mnemonic represents 128 bits of entropy and that is why it is not possible to randomly find one with balance in it.
