Figure out variable that holds volume by service

[SeanMcOwen]

After each relay, there is a probability that the request logs as a relay done on the service (based on probabilistic mining). When it comes to reward disbursement, what does this variable look like? Does it give an accumulated number of requests over a time period? Is it a stateful metric that can be computed from block history?
