Find out how many times a player has won PB/MB
New IndexGain feature has just been released where you can find out how many times a player has won MB/PB and their yield since August 2017. https://twitter.com/IndexGain/status/1026768402277380096
Just be aware that the earliest days of PB there were only 200 players on the index so there were many days when only 1 player could possibly win, off the top of my head - Perisic, Icardi, Januzaj, Bonnucci and Donnarumma all won PBs when no-one else / very few players were eligible
Personally I ignore all PB wins pre-Jan 1st when the index was still expanding. Early scores are useful, wins are misleading.
