I think you are refering to the convert all logfiles option (which re scans for all time records)?
note , doing that, will not zero the record rain rate , or check for that from the logfile
as the logfile only records the rain in the last minute (which is not the same as the instantenous record high rain rate)
maybe you reset it via action, reset selected all time records, or similar?
but you could use, say, excel, loaded as space de limited, to find the maximum rain in the last minute
as for the other parameters, using that convert all logfiles, which search for a lower all time record low windchill
solar or uv is not reset or re scanned via the convert all logfiles
