Instead of thinking about it as a way of trying to identify cuts, I think of it as training your referencing ability. You can find what frequencies you're missing compared to your reference fairly quickly that way.

So I'd say don't worry about seeing the A/B as cheating, because every track is different and what's considered a cut in one track might be considered a boost in another.

Anyways, I hope that's helpful!
