I did actually do this somewhat and that's what led me to do the overall sim but to be honest I didn't treat it very scientifically. I only did play now but at the CFM settings. I also didn't check injuries off. It was lazy attempt and I can't prove too much so I'm 50/50 as to how much it affects supersim. My initial view is that at least for RBs it shows an affect. But then again as happened above it was likely the placebo affect. Maybe if I have time I'll try but i can't promise anything.
