Steve said that Cumulus was updating it's readings around every 15 seconds from the display unit. I suggested the readings appeared to perhaps actually change every 60 seconds or so in Cumulus's own display.

This compared to EW's own maximum update settings of 5 minutes between updates - probably to keep the size of the .dat file down to a more reasonable size. Just a thought - perhaps the (much) faster update could be retained in EW, but it could have discarded all but one data set in five to achieve the same file size?

My manual's back page suggests some of the data items in the LCD display base unit are updated every 48 seconds. Has anyone noticed/checked if this applies to all the data items? Does the frequency of update increase, if for instance the wind speed rises (as some WS do) or is it fixed at 48 seconds?
