(2) While I had six years (2010-2015) worth of point by point tennis data, it actually is not enough to use it as a source of truth. The resulting graph looks like this: As anticipated, this graph goes to 0 to 1 on both tails fairly quickly.

For instance, if you have 10 new matches, 7 of which led to wins, you can merely update a, b with a+7, b+3 respectively. If b is larger than a, then p's distribution is more concentrated to 0.

Starting to master the use of power and spins and beginning to handle pace, has sound footwork, can control depth of shots and is beginning to vary game plan according to opponents.

Extrapolation caps estimated points for the whole career to the 10 times points earned in the Open Era. With the base model in place, we seek to examine factors that can help us adjust / make our probability predictions with more certainty.
