max_coefficients = (4.60 * 1 + 3.85 * 1 + 3.75 * 1 + 3.65 * 1) = 15.85
p1 = (284.21 * 3.85 * 1 + 610.17 * 3.25 * 1 + 57.14 * 1.90 * 1 + 0 + 0) / (3.85 * 1 + 3.25 * 1 + 1.90 * 1 + 1 + 1) = 289.62090909090915
p2 = (610.17 * 3.25 * 1 + 284.21 * 3.85 * 1 + 57.14 * 1.90 * 1) / max_coefficients = 200.99873817034702
