Hi Caroline.  I don't know ...

Hi Caroline.  I don't know that its that important that the actual use and the platform match.  A typical utility only reads once per month manually,  even the most accurate AMI system rarely reads more than 4 times per hour, both of which will likely lag actual use.   That said, we have had some clients that like a reading every 5 minutes and have supported them.  I think it's most important to understand your clients need for the information to assess the proper read interval.  I hope this is helpful.
