I don't care how much about the latency between when the power meter computes a result, and when it's available to my Linux box. But I *do* care a lot about the precision of the time sampling in the report.
NUT itself does not include timestamps in the output. When you query upsd, you are receiving data that can be up to [pollinterval] seconds old (plus any serial/USB transaction latency), which isn't a problem for basic status monitoring related to UPS health. Your application sounds like it needs at least one or more orders of magnitude more precision than what NUT can offer right now.
You could certainly modify the code to add that timestamp, but as mentioned elsewhere in this thread, you'd need supported equipment as well.
