I did include the inputs, with the assumption of high efficiency feed for industrial meat production, i.e. a feed conversion rate of about 6.
This paper is about shifting animal corn to human corn, not about shifting animal corn to broccoli. Corn produces about 6 times as many calories per hectare as broccoli.
Not even close. Did you forget to consider the inputs into meat?
If you want to check against someone else's math, here's a paper that claims we can increase global calorie availability by 70% by shifting crops grown for animal feed (40% of crops in USA btw) to crops grown for human consumption: https://iopscience.iop.org/article/10.1088/1748-9326/8/3/034...
