Dice Roll Dillemma

Good day!

I have been researching the dice roll seed generation and came to an understanding that this is how its done by hand.

Dice to BIP39 Word Memo

Roll the die 11 times.

Convert each roll:

1-3 = 0

4-6 = 1

Write the 11 bits in order.

Under them write:

1024 512 256 128 64 32 16 8 4 2 1

Only add the numbers under a 1.

The result is your number from 0-2047.

If your word list starts at 1, choose result + 1.

Repeat for each BIP39 word.

Example:

11110011000

→ 1024 + 512 + 256 + 128 + 16 + 8

→ 1944

→ word #1945 on a 1-2048 list.

Important: For a 24-word BIP39 seed, the underlying entropy is 256 bits, and the final word includes the BIP39 checksum. Don't independently choose all 24 words.

So, savvy Bitcoiners please let me know if I get it right or how I messed it up.

Thank you for your time!
