The current algorithm that determines Top Sport for Year in Sport is inaccurate. I walked 200 miles this year, and ran 1,800 miles--yet my "Top Sport" is walking. The reason is that my runs are split up between "Trail Run" and "Run" both of whose individual count of activities are less than the number of total walks I did since I typically go for a walk in the evening. You could fix this by either determining "Top Sport" by the number of miles NOT by number of activities, or if you are intent on counting activities, then count "All Run" instead of the subcategories. Either way, the algorithm is horrible and as a paying subscriber who ran 1800+ miles, one 100-miler, 2 50-milers, and 2 50Ks this year, it's reveals a lack of seriousness on your part to reveal to me that my top sport is "Walking" in the year in review feature.
