I can believe that trading some time lifting weights for time on the bike is beneficial for USA type racing, but this 4:1 ratio is really surprising. With just 4 hours in a week of riding (which might be just 1 short and 1 medium length ride), you would spend 16 hours in the gym? I can't imagine what you could do in the gym for more than about 6-8 hours in a week.
For track, he was riding 1-2 hour week. Increased to 3 hours for a couple weeks before crit.
