"In fact, new managers cannot work magic. The short honeymoon after the new man takes over is easy to explain. Typically, the average club earns 1.3 points a match. Typically, Bridgewater found, a club sacks its manager when it averages only 1 point a match—that is, at a low point in the cycle.
"Any statistician can predict what should happen after a low point: whether or not the club sacks its manager, or changes its brand of teacakes, its performance will probably “regress to the mean” – or in ordinary language, return to normal. Simply put, from a low point you are always likely to improve. The club may have hit the low due to bad luck, or injuries, or a tough run of fixtures, or—as perhaps in Manchester City’s case in 2009—the time it takes for a largely new team to gel. Whatever the reason for hitting a low, things will almost inevitably improve afterward."

The point is, Moyes is a better manager than Dyche and has changed things to get better results. What you saw was not a "new manager bounce" but the outcome of putting someone who is actually significantly better at the job in charge. Guys like Irvine are also better than the coaching staff that was at the club under Dyche.
We may not be getting the results we have deserved, but that is due to the fact we cannot make the most of the more plentiful opportunities we are creating than due to the system itself.
