Unfortunately the issue will remain whilst the gauge-data.txt values are formatted to the likes of 1 decimal place. This issue also exists with other PWS software that produce a similarly formatted data file for use by the SteelSeries Weather Gauges. Changing the underlying units to the units normally used by the user will eliminate the issue for those units, but the issue will eventually recur if different units are selected for display (for example, your MPH values will now be accurate but someone observing your gauges in km/h will eventually see a similar small error, admittedly they won't have a console in front of them to highlight the discrepancy :) )
