Taekwondo and Savate should be lower. I don't see any reason why you would rate Japanese Jujitsu and Judo any differently. Keysi Fighting Method and Kenpo should have the same score.
I don't think you understand what Jeet Kune Do is. I would just take it off the list. Why would you give Silat a 1? That score is just goofy considering the other arts you ranked much higher?
Also, Kung Fu? You do know that "Kung Fu" incorporates many different styles right? Many of which make up the principal techniques of sanshou (which you ranked really highly).
If you ranked BJJ a 2 for multiple attackers, why didn't you also include that score for other grappling arts like wrestling? Or, like with Savate, give it a qualifier like "2 for grappling exchanges".
This whole list is a mess.
Savate is boxing + karate kicks. Pretty decent for the streets.
Taekwondo is definitely not ideal, but it's not as bad as the ones below it.
There are many unrealistic Japanese Jujitsu styles.
Keysi is a bit more realistic than Kenpo.
I've heard it a million times. "Jeet Kune Do is a philosophy!!!!!"
The places that say that they teach Jeet Kune Do primarily teach Wing Chun.
Silat looks like little kids fighting.
Kung Fu as a whole is goofy.
Sanshou is very real unlike Kung Fu.
Wrestling, Judo, Sambo, etc. are mostly standing grappling.
Brazilian Jiujitsu is mostly ground grappling.
Ground grappling is less effective against multiple attackers than standing grappling.
Striking is way more useful than standing grappling or ground grappling for the streets. Ground grappling is easily the worst.
