max_coefficients = (4.60 * 1 + 4 * 1 + 3.75 * 1 + 3.05 * 1) = 15.399999999999999
p1 = (666.67 * 1.20 * 0.14 + 266.67 * 1.20 * 0.29 + 0 + 0 + 0) / (1.20 * 0.14 + 1.20 * 0.29 + 1 + 1 + 1) = 58.54333128457284
p2 = (666.67 * 1.20 * 0.14 + 266.67 * 1.20 * 0.29) / max_coefficients = 13.359740259740262
score = 58.54333128457284 * 0.5 + 13.359740259740262 * 0.5 = 35.95153577215655
