pi, just on points #4 and #5:
#4: I thought the rankings were determined by % of RAW study scores over 40, in which case having lots of kids get low 40's in BM would help, not hinder?
#5: Trust me, the physics department at MacRob is absolutely horrible too. My friend had to basically teach herself the course, since she didn't get a tutor. But in fairness, MHS has a larger physics cohort than MacRob so a crap physics department would affect stats a lot more.
#4 We have more 30s (esp in the 37-39 range), that drags us down. This point was just my opinion, I'm not sure if its even valid tbh 
#5 The number of people in mhs doing phsyics is like 4x Mac.Rob's number though.
But these are minor points, poor subject selection is our fault. #3 is far more significant imo
Ahaha I don't know if you'll win just by cutting off 100 students. We can't really test it, but my hypothesis:
1. If you cut 100 students at random, then it will make minimal difference and MacRob will probably win.
2. If you cut the
bottom 100 students then yeah, MHS will win, but that's not really fair, is it? MacRob has a smaller cohort, so if we, hypothetically and purely statistically, cut just the bottom 30-50 people then we'd do much, much better too.
