Yes, you are totally correct. The original version I had a few years ago had CSV logging. My personal preference is to use .bin logging because it means that the script does not need to do anything to add logging for additional sensors. Take RPM for example, it just works without needing to access it from scripting.
But the point of this script is to offer people with a good starting point. I do not intend it as a app that will fit everyone’s use case. If csv logging is preferred by a given user, it can be added by said user
