Among other reasons this is because normal performance is seen when things are normal. A provider's performance guarantee is presumably going to have a more demanding specification than just "you'll see numbers like this most of the time".
It may actually be that the performance guarantee is a paper-dwelling construct, and has little or no form in the actual network. I have certainly come across providers in my past for whom performance guarantees were necessary in order to be able to bid for projects, but the cost of deploying infrastructure to support the guarantees was much higher than just giving a few refunds now and then. As such the guarantees didn't really exist outside the billing department. Joe
