may not have been that clear from Tom's response - but there are two main areas involoved here: 1. [StdWXCalculate] where all options should normally specify prefer hardware for vantage stations. if rainRate is set to prefer_software then weewx calculates the average rate over the archive period 2. [StdArchive] where record_generation is usually set to hardware. However if record_generation = software is set weewx calculates all values as averages over the archive period.
I do not know what happens if rainRate is set as prefer_software but record_generation is set al hardware. ie I do not know if weewx overrides the hardware record values with its calculated rate or not.
