two quick points:

(1) the way your plot your results, i.e., varying both delay and loss rate on the x-axis but plotting one line, is very confusing

(2) simulating loss rates much above 1% is likely going to be pretty uninteresting, given that QUIC (and TCP, FWIW) have congestion controllers that will struggle to even deliver useful throughputs in these cases
