KM is based off of boxing, wrestling, and classic Jujitsu that was part of Eastern European hand-to-hand fighting methods in the 1930's. I know it's adopted some BJJ techniques for ground fighting. It wouldn't surprise me if FMA provided some material for weapons training, though I haven't personally seen anything to indicate that.
I don't know why you thought something invented by a guy who grew up in Slovakia would be "based off of kali".
I think you have a point there.
I heard Krav Maga is based off of kali
