1. shares ratio will sometimes be under 1.00 when you have a rejected share.. .99 is not a prob. if its worse than that maybe one of your cards is overclocked a little to much and is producing rejected shares from time to time.
2 i'm not sure about the ping it all depends where you live and your internet connection but 125ms isn't to bad
3. i don't know what you mean by share above target?
