As far as what is cs ratio, and what 100%, 150%, 180%, and 200% and all those numbers mean, it's quite simple. At 100% cs ratio, it means the rear wheel will rotate once more than the front wheel. So the rear will will turn twice, for every time the front wheel turns one. At 150% the rear will will turn 1.5 times more than the front wheel, and so on. There are many YouTube videos that demonstrate this with tabs of tape on the tires so you can see the difference in rotations.
