Timers and Performance Q - Games

I am wondering if anyone can share with me what they set their Timers to.

I’m doing multiplayer games, so I am not using onEnterFrame.

I have set my flash player default setting to 70FPS, which will probably average around 30-40FPS for people with good pc’s. My scripts run at a 35MS interval, about 30SPS(scripts per second… lol.)

Should I add in a FPS check, and lower the player quality if users average fps is too low?
