To clarify a few benefits of this definition;

• We CAN benefit from spending more energy on a decision.
• We CAN delude ourselves more and more if we don't second-guess previous decisions (at our detriment to economy/social situation/professional situation/love life, etc). Previous decisions are just memories, we hold no more duty to them than the calories we spent watching the TV last night.
• We CAN make efforts to control for biases if we make an effort.
• We CAN make efforts to make higher quality decisions with even minor effort, especially if we mull over the decision until the actual deadline instead of jumping on the first decision that falls into our mind.
• WITHOUT this type of free will, more effort on decisions would be pointless, because we'd be just as likely to hit the best possible decision at 1 calorie spent as an infinite calories spent. So we should be happy we have this "lack" of free will as philosophers previously claimed we had, and instead have this free-will-within-causality.
