Look at the actual cycle time on the extractor when you submit the changes, with a program duration time of 1d 30m I’m betting you have an extraction time of once every 15 mins or less. The extractor itself is showing you what its pulling per CYCLE not per hour.
If the link loads above is an example of what I’m refering to cycle shows less than the average per hour because its just that an average of what youll get over the entire program duration not what you will get every cycle.
This is the same program from the same extractor as above.
