I can only speak for my area and somewhat for the original posters area. A patient whistle is something I do knowingly and am in total control of. It depends on time, severity and situations among other factors. In some game situations I wouldn't dare to do this because I would just need to look for security as soon as I make the call. I would do this in a game on any level except college. IMO a college evaluator and/or assigner does not want this to be a habitual thing. Also the theory of just getting it right or helping your partner in their area is something that is talked about more than it should be put into practice. Once again my opinion. I'm dedicated enought to officiating that I want to work to get my own angles in my primary and will be pissed at myself if I continually need help in my area.
I had more to say but I have to go paint!

5 or 6 in a high school game is too many TR.
