I think you found the reason… those numbers all seem pretty high for ~7.5 hours per week.
To compare, my weight bounces around 150#. I only get up to 3,000 calories a day when my average weekly volume is around 15 hours.
Normally I don’t track calories; it works fine until all of a sudden it doesn’t. But I did for a few weeks when I was working with our nutritionist, Rebecca. With her help, I had a plan based on my age and activity level. I was eating about 3,000 per day during heavy training with a baseline diet of around 2,000. Also, I would periodize my nutrition; calories would fluctuate with the daily load.
Rebecca has a bunch of helpful rules of thumb that worked better than counting calories.
