During the 2018 U18 in St. Andrews we had a request from coaches that detailed stats (shooting percentages) be kept but not displayed online on our website. We will almost certainly get this request again next year and I think it would be useful feature to add to Curling I/O. I'm not sure about implementation details but there has to be a way to allow access to these stats on a per-user basis (email address perhaps). Maybe this feature is best handled through our proposed stats.curling.io portal?
