So basically the same as conor2796, except Q14 (Relief is high-low, so 180-120 = 60m), Q16 is semi-logarithmic and Q18 I got A (1950-1970 - wasn't sure about this one though, I tried to work out rates and I got that as the biggest, 466% change vs 157% for C)
No guarantees these are right though! Just what I put!
