FS9 Realism Settings...

Hi all,I seem to be becoming a bit of a "realism" junkie, and so I downloaded RealAir's C172 flight model yesterday, as I had seen a great deal of positive comment on it in this forum. And rightly so; it is excellent. Certainly doesn't do weird things during take-off like my default C172 did! Deciding now whether I want their payware offerings too...However, I notice in the read_me file with the C172 flight model that it says set the p-factor (prop effect) slider in FS9 realism settings to HALF-way to have realistic prop effects. Now I naively thought that pushing the slider ALL the way to the right gave me realistic effects... what is going on?! What realism settings do you guys on here use? I fly with all my sliders pushed to the right, thinking that this is most "realistic", however this comment from RealAir - guys who know a lot more about "realism" than I ever will! - has caused me to rethink. Any thoughts, ideas or comments?Cheers,Paul...
