Wow. Moogs and johnq need to get into my office ASAP. There are some good treatments for OCD. Will only take about 3 months with some intense exposure sessions. I'll give you both AN discounts.
Seriously, interesting stuff. If you do include salary, I think it needs to be calculated relative to others in that particular sport. I don't think it's fair to compare raw salaries amongst sports because some are more expensive than others.
