"We are excited to announce the release of Smaart 8.5. I work a lot in pretty windy environments so that's something important to me. The point is that if you read the article you might not even try RMS avg since it shows no upside to it, and there is actually situations when it is advisable to use it as far as I know. Also for the same reason, any movement at all of either the system or the microphone (a little swaying on a hung system or a not entirely stable mic position) will have similar effect as far as I know. If there were no such cases, why include the option in the software? My understanding is that it is better not to use vector averaging when working with wind as it will change the direction of the vector received in each of the data points you are averaging, so it will show you less accurate data. All interesting information, but it surprised me that he didn't mention any instance where RMS averaging was advantageous. I read a Merlijn Van Veen article on PSW that was basically showing the advantages of vector averaging compared to RMS averaging.
