    4,5 The option for refresh rate is not very helpfull as all of them seem to be too close together and bassically you have very fast, slightly faster, a bit slightly faster and faster just one bit more. Great tool tough, good sensor readings and very well done graph with auto scaling and stuff. Good job!
