Are sports card breaks worth it?

A break sells spots (usually teams) in a live box opening. To judge one, estimate the expected value of your spot: the chance of each relevant hit for your team, multiplied by its sold-comp value, then compare it with the spot price. Most spots receive mostly base cards, and the breaker's margin is built into the price, so treat breaks as entertainment.
