In order to come up with ERC, a two-part equation is necessary.

A)
PTB = 0.89 x [(1.255 x (H-HR) + 4 x HR)] + 0.56 x (BB+HBP-IBB)
*PTB (Pitchers Total Base Estimate)

Let’s use Jason Schmidt’s 20004 season again. Here are his totals:
Hits HR BB IBB HBP BFP IP
165 18 77 3 3 907 225
*BFP = Batters Faced Pitchers (total batters against)

PTB = 0.89 x [1.255 x (165-18) + 4(18)] + 0.56 x (77+3-3)
PTB = 0.89 x [1.255 x (147)+72] + 0.56(77)
PTB = 0.89 x [184.485+72] + 43.12
PTB = 0.89 x [256.485] + 43.12
PTB = 228.272 + 43.12
PTB = 271.392

B)
ERC = [(H+BB+HBP) x PTB / (BFP x IP)] x 9 – 0.56

ERC = [(165+77+3) x 271.392 / (907 x 225)] x 9 – 0.56
ERC = [245 x 271.392 / 204075] x 9 – 0.56
ERC = [66491.04 / 204075] x 9 – 0.56
ERC = [.326] x 9 – 0.56
ERC = 2.934 – 0.56
ERC = 2.374

Therefore, Jason Schmidt’s ERC in 2004 was 2.37.
