Thanks for the interest in resolving this, Andrew, I understand your persistent cache argument. The reason I don't personally use "Total" and DO use "Delta" is more around what the collector does should it not see some of the updates and suddenly gets one that shows large counter values. This could mistakenly result in showing huge traffic over a short period incorrectly. This is particularly true if you do as Brian suggested and are setting the flowStartTime based only on the current record view. Brian, thanks for your detailed explanation. Everything with the exception of flowStartTime was as I am currently doing. I had perhaps mistakenly taken the approach that keeping the flowStartTime as the "conceptual" start rather than for this reporting period would make it easier for the collector to understand what was happening. Not actually sure how I will co-ordinate reseting that time on export yet :-) I would suggest that this sort of situation and Brians explanation be added as an example perhaps in 5101 or even 5472 as it would help with Collector interoperability I am sure :-) Thanks again.
