2017 sees the British Road Race and Time Trial champs head into the Irish Sea to tackle the very famous roads of the Isle of Man with the road races taking on the classic IOM TT motorbike circuit (twice for the men) before a number of laps of a smaller circuit just outside of Douglas. The time trial tackles a lumpy circuit with a couple of stiff pulls and next to no flat road.
Since the introduction of the Explorer Score and Explorer Max Square there have been requests for some sort of metric to represent the maximum number of connected Explorer tiles. The recent improvement in the calculation of completed Explorer tiles sparked a very active discussion which resulted in the refinement of the concept and the creation of the Explorer Cluster. The Explorer Max Square provides a hard-core challenge but can be tricky for people who live in geographically challenging areas or have key tiles which are completely inaccessible. This is where the Explorer Cluster looks to provided a more level playing field.
The way that completed Explorer tiles are calculated has remained pretty static since its inception in March 2015 which included some, less than precise code to try to get around some of its known limitations (detailed below). I’ve now refined that code to improve the accuracy and also speed up the processing quite considerably and also introduced a method to get a definitive list of tiles for an Activity. This improved accuracy will of course result in a number of tiles that were previously marked as ticked now showing up as unticked (and potentially affecting your max square size) but only tiles that you never actually visited in the first place 🙂
