Estimated Dynamic NTRP Ratings for the ATP through the Australian Open

I introduced doing calculations of Estimated Dynamic NTRP Ratings for the ATP a few weeks ago and I'll be updating the ratings periodically, this post being the first update.

The list below includes the Australian Open and other tournaments played in January so you can see how player's results there affected their ratings.  And I'm showing the top-50 this time around.

Rank	Name	Rating
1	Novak Djokovic	7.08
2	Andy Murray	6.97
3	Roger Federer	6.96
4	Milos Raonic	6.84
5	Tomas Berdych	6.73
6	Gael Monfils	6.73
7	Stanislas Wawrinka	6.72
8	Kei Nishikori	6.72
9	Rafael Nadal	6.69
10	David Ferrer	6.68
11	Roberto Bautista Agut	6.67
12	Jack Sock	6.63
13	Marcos Baghdatis	6.63
14	Bernard Tomic	6.62
15	Marin Cilic	6.62
16	Grigor Dimitrov	6.62
17	Nick Kyrgios	6.61
18	Joao Sousa	6.60
19	Jo Wilfried Tsonga	6.60
20	John Isner	6.58
21	Gilles Simon	6.58
22	Dominic Thiem	6.55

24	Guillermo Garcia Lopez	6.54
25	Viktor Troicki	6.53
26	Hyeon Chung	6.53
27	Kevin Anderson	6.52
28	Philipp Kohlschreiber	6.51
29	Mikhail Youzhny	6.51
30	Gilles Muller	6.51
31	Lukas Rosol	6.50
32	Leonardo Mayer	6.50
33	Illya Marchenko	6.49
34	Fabio Fognini	6.49
35	Andreas Seppi	6.48
36	Alexandr Dolgopolov	6.47
37	Ivo Karlovic	6.46
38	Teymuraz Gabashvili	6.44
39	Taylor Harry Fritz	6.44
40	Jerzy Janowicz	6.43
41	Thiemo De Bakker	6.43
42	Feliciano Lopez	6.43
43	Steve Johnson	6.42
44	Ernests Gulbis	6.41
45	David Goffin	6.41
46	Robin Haase	6.41
47	Edouard Roger Vasselin	6.41
48	Vasek Pospisil	6.39
49	Denis Istomin	6.39
50	Borna Coric	6.38

Novak is at 7.08, remarkably close to the 7.07 he ended 2015 at, and maintains a clear lead over Murray and Federer who are very close, then a drop to Raonic, and another drop before the players lead by Berdych bunch up a lot more.

Again, the NTRP algorithm is very much weighted towards what you've done lately, so the above is a reflection of how players have started the year and less about how they did last year, particularly early in the year.

Women's to come.
