Not sure what CP wants but just look at average points per tenure, then average points of the last ten and first ten games after a change.What numbers do you want specifically?
I saw similar stats for the Prem when they did a piece on it and they proved that by and large, new manager bounce was a fallacy. There are always exceptions but a good squad will remain a good one and a bad one likewise unless there is a window handy...
