As an example (not sure if applicable), you could do some calculation and get an alternating series as the result: R = 1 - 1/2 + 1/3 - 1/4 ... If you "explain" the positive part as being contribution from field A, and the negative part as a contribution from field B, both would be infinite, but the reality might be that splitting them is nonsensical.
