I
think you are looking for the "Sampling" settings in WC Prefs->Misc2, bottom of the window.
"Sampling Rate: 1/2/3/4/5/10/15/30 minutes". I use 2 minutes. I also have "Adaptive" checked.
Davis hardware usually checks and send data to the Console every 2(?) seconds, but WC doesn't need that much data to work well. The faster you set the sampling rate, the more disk space you will use. "Sampling" is building a database which you can view with WC->Tools->Data Viewer/Editor. You can fill up the largest screen you can buy!
