One other thing may have happened, that happens with many companies.
The company could have 1000 shops and if the fill 950 within the deadline they meet the metrics, if they fill 949 they may get hit with a penalty that reduces the revenue to the company for each of the 949 shops.
So they offer a high bonus to get over that 950 shop threshold. As soon as the minimum standard is met and pass through editing the bonuses on the remaining shops for the time period may revert to the normal bonus. The MSP is still trying to fulfill the 1,000 shop requirement, and each of those shops from 950 to 1000 may get a premium for the MSP, but they do not carry the same financial weight as hitting the minimum promised goal for the client.
This is an example, the information is based on conversations I have had with schedulers and owners and could apply to a number of projects. The goals are probably closer to 95-99.9%, rather than the wide range I mentioned here.
