Component ERA (ERC) is a Bill James statistic that estimates a
pitcher's ERA based on his peripheral statistics rather than the runs
allowed (since the number of runs can be biased by the next pitcher
allowing the first pitcher's runners to score and plain old luck).
The term is sometimes used more generally to refer to any method
with the same objective.
James' ERC is based on the Runs Created model of run scoring, and
is calculated as follows:
ERC = (H + W + HB)*PTB*9/(BFP*IP) - .56
where PTB = .89*(1.255*(H - HR) + 4*HR)+.56*(W+ HB - IW)
If the result of (H + W + HB)*PTB*9/(BFP*IP) is less than 2.24, then
instead of subtracting .56, multiply by .75.
