Let's play a game

an experiment, predicting all the winners of round 1, will be probably a higher margin of error given changed conditions, possibly more upsets to break the trend, but either way, but we shall plough on regardless

STEP 1- Identifying number of favs winning R1 last 5 years at RG

ATP - 53 - 51 - 49 - 50 - 53 - Average 51.2 (80% of R1 favs winning)
WTA - 47 - 46 - 46 - 46 - 45 - Average 46 (71.9% of R1 favs winning)

So I shall be looking to predict 13 non favourites along with 51 favourites in ATP.
I shall be looking to predict 18 non favourites along with with 46 favourites in WTA

Odds are from matchstat, so nvm the increments.

Kasatkina hurt her ankle bad last week, do not know how she is, but her opponent is rank, so maybe she get through that on one leg, but still, a question mark, decided to put soft hands through god bless her but do not be surprised if she retires during her match.
