Why is this thread full of wrong information?
As for electrum they use same process or should I say script as the Bip39 format for their custom words with the exception of the words
Wrong.
Electrum uses the BIP39 wordlist, but its own algorithm for generating seed phrases.
When you store words in shorten format, the possibility of you losing your wallet is high because some words that you shorten will have the same alphabets like the ones you mentioned above and more.
The first four letters in each word of BIP39 wordlist are unique.
If you write down only the first 4 letters of each word correctly without any typos and pick the words from the BIP39 wordlist when importing your seed phrase, you are completely safe.
If you generate a new wallet from Electrum, you will not able to retrieve your coins if you use other wallet.
You can import electrum seed phrase into bluewallet.
Sparrow also allow you to import electrum wallet files.
My main concern was that Electrum is using different standard, so when I generated new seed words there WAS some words that could be reconstructed in two ways if saved as 4 letter word.
Electrum and BIP39 use the same wordlist, but a different algorithm for generating seed phrase.
Electrum used a different wordlist in the past. Since new versions of electrum allow to import old seed phrases, electrum still suggests the words from the old wordlist.
Words "
Groundground" and "commit" that you mentiond in OP existed in the old wordlist, but
not in the current wordlist.
The words used by BIP 39 are quite different from that of electrum.
No, electrum and BIP39 use the same wordlist.
Their word list and checksum rules differs and if you try to enter a BIP39 seed into Electrum
it may consider it invalid and reject it
Again wrong. Electrum allow importing BIP39 seed phrases.
