Oh, well pardon me! English is not my first language and that is the word that is used in spanish where I live.
The current LSB sign is the same as the ASL. LSB is just recently forming itself into its own sign language. So I would take a guess that a good 55-60% is the same as ASL. For LSA and BZS, I have no idea. Education is poor, so to effectively reach everyone equally, mimica (Better not try english) is what I use in place of the signs that I don't know/want to use. Yet, expert signers tell me I do very good.
I hope that answers your questions. Thank you.
