No, that's still involving export. What should the MP do if the flow ends *but isn't exported* ? Just the same as when the flow *is* exported. So the definition of deltaCount is independent of export, flow records, etc. So the definitions have to be about the metering time, and particularly that we've started metering again. However, we can't write that, because some implementations may not hold state that tells them this. So all we know is that totalCounters meter from the start of the MP, while delta counters meter a potentially shorter interval, reporting the value metered since the start of that interval.
