max_coefficients = (4.20 * 1 + 3.75 * 1 + 4.05 * 0.71 + 2.80 * 1) = 13.642914999999999
p1 = (641.03 * 1.80 * 0.86 + 608.70 * 1.40 * 1 + 0 + 0 + 0) / (1.80 * 0.86 + 1.40 * 1 + 1 + 1 + 1) = 309.8095504124333
p2 = (641.03 * 1.80 * 0.86 + 608.70 * 1.40 * 1) / max_coefficients = 134.9513648659396
score = 309.8095504124333 * 0.5 + 134.9513648659396 * 0.5 = 222.38045763918643
