Maybe 50 is not the number for you. Maybe it's 30-40 or whatever. As I have said, the main goal should be for people to grasp the concepts behind the training advice and apply it to there situation. In my case, I am very unhappy with my 1:27-1:28 HIM run times. For me, knowing that the run leg is my weakest event, a 50mpw avg is well below what I have targeted for myself. For someone else 30-35 may be the target.
The main principles are not to fixate on a number but to set a goal and stick with it for 3-5 months to really give yourself time to improve, while maintaining some frequency in the other sports. The fitness levels in the other events will come back quickly once you resume normal training.
Eric, I can guarentee that if you increased your running volume by 25% and held it there for 4 months, fading late in a race or dreading the final leg of the race will be a thing of the past.
