It seems like this tipster is cheating on his stats.
Each month he declares about fifteen games as being draws when they are not. You can verify the statistics by yourself.
EDIT for answer : On your statistics files, you consider some matches no draws like draws. Example on january 2021 : 01/01/21 Everton - West ham was 0-1 (that's not a draw!) and you consider it a draw. Same with Talleres Cordoba - Banfield (3-2) last 4th january, Avranches - Laval (2-1) the 15th, Nexaca - San luis (1-0) the 15th, etc etc. There are 10 like that in the first three weeks of January. An explanation would be welcomed, thanks
