Here is a shot of my guiding graph for the G-11, typical graph for a giving night. 22 lb load plus 22 lbs of weights.

One thing about this and the EM200 chart - you really want to look at the chart with unsmoothed data. The reason being that it's the very short term (a few seconds) smoothness that matters the most if you are autoguiding. When I had my EM200, I wouldn't hesitate to use 12-15 second guide exposures (and have used 30 second guide exposures with my NJP). I've never heard of anyone using guide exposures of more than a couple seconds with a G11 at any significant image scale (< 2 arc secs / pixel or so).
