The question might not be all that clear, but let me explain. So you decided that you want to be competitive in RUF Cup. If you do only 3 races a week in the series, the best one matters therefore there is no stress about throwing a race away, or doing something stupid. That way you won't really gain much iRating, even by winning, in a short ammount of time. Would it be advised to pick another serious you have decent speed in and abuse the official queue or just simply race more on the series you are dedicated in?
