Sorry @Robert.Wall I replied in haste last night. I see what you mean now, I can see that that would be a good solution as well. A complicating factor is how to deal with feed engines that dont have set intervals e.g PHPTimeSeries and MySQL. Perhaps a parameter could be passed to the process that would effectively do the same thing averaging over a set time period but being user defined from the input processing UI rather than derived from the feed…?
