This example shows that the forward match factor is 1.0, but the backward match factor is only 0.1333. And the combined match factor is simply the bigger one of forward and backward factors. Is there a way for the combined match factor to use the average of both factors when one of them is too small? Or is there a way to make it not a match when one of the factors is too small (below a certain threshold like 0.2) even though the other one is big.
