It might be more accurate to break up meals by primary and secondary students and then sum them, since primary students probably eat a lot less than secondary students on average.
You also divided the number of animals per person per day by 3, I assume for breakfast, lunch and dinner. Do people in the UK usually eat meat for breakfast? And do they eat more meat at dinner than lunch?
I don’t think these would have huge effects on your final numbers, though.
Thanks for highlighting these, these are both really good points. I really appreciate the thought provoking comments and questions you’ve left generally so thank you!
Regarding point 2: In hindsight, it would have probably been more accurate to weight each meal but their relative ‘animal-content’ e.g. 0.5 for dinner, 0.35 for lunch and 0.15 for breakfast. You’re right in that most people won’t be eating meat for breakfast (except on weekends I imagine) so that should be weighted down. If I used the weights above, it would probably be very similar to the 0.33 I’ve basically assumed in my original model so you’re right in that it probably wouldn’t change much.
Regarding number 1, again it would make some to have some kind of subjective weighting system based on the size of the meals. I did add a little epistemic uncertainty factor to the top of my post of about 70-80% as like you and Ula have pointed out rightly, there’s definitely more factors that I could have included in my analysis but I didn’t for simplicity/time.
