When you pin My Commute as a live tile, it tells you the estimated time of your commute at about the time it knows you want to leave, but, sometimes it shows a tick in the tile, other times it shows an exclamation mark (examples of both below). Is there a legend for these, or some way of knowing when the commute will have a tick or exclamation mark (or any other symbol?!), such as it has an exclamation mark if it's n standard deviations greater than the mean journey time? I know there has to be a cut off / boundary, but in my instance, the difference between 1 hr 22 and 1 hr 24 wouldn't immediately seem to be the difference between 'good' and 'bad'
It appears that the algorithm for suggesting what constitutes a 'delay' isn't the same in both directions - this morning, my phone helpfully told me that a 1 hr 14 journey needed an exclamation mark (so why not the 1 hr 22 journey yesterday?)
