once drove the stilo from just below sheffield to home with --- range (usually comes when below 30 miles).... and its a 35ish mile journey to home
I did that once in Bismarck - it was reading 22 miles which should have been more than enough but I forgot there was a road closed which meant I had to go the long way round. About 25 miles later I rolled into Asda as it rolled to --- (which = 0).
