Hi Gary, The console data is timestamped with odd minutes , but the other data is timestamped with even. I'd prefer it if they were the same, but I'm not sure how to sync them. I checked the console clock and its correct.
The driver I'm using is *[Interceptor]* * # This section is for the network traffic interceptor driver.* * # The driver to use:* * driver = user.interceptor* The tags in the report i'm using are *$_span.windSpeed.max.raw, and $_span.windGust.max.raw* I've read the wiki entry page and I'm now suspicious that the tags I'm using are wrong. May be this will explain the discrepancy with the values shown on the console.
