Winning percentage minus opponent's ranking

MuryGOAT. Ergo, since Federer is a subset of every single male tennis player in history, we can deduce that Murray > Federer.
Fed also never beat a 20 GS champion on his way to his titles, what a newb. Even Wawrinka beat 20 GS champion in one of his majors. Lew's logic, Fed can't be the best because he never beat himself. Of course if you are nr.1 you can't face nr.1 player lol.

Well-played. I like it.
 
example: 2015 Djokovic won 93.18% of matches facing opponents ranked 17.8 on average ---> 93.18 - 17.8 = 75.38

> 60.0 scores:

2015 Djokovic - 75.38

I was just using the fed fan logic. Of course Djokovic was peak since 2011, and Fed didn't end his peak in 2007.

Djokovic has negative h2h versus Wawrinka in Grand slam finals, 0-2. How can you be the goat if lower tier player owns you in Grand slam finals? Imagine if Ali lost two times vs lower tier boxer in his peak? That's worse, at least Fed has negative h2h versus great players in GS finals.
 
It's one of my greatest thread. I'm very proud of it.

It's much harder to have a high win percentage against high ranked opponent. This method measures it.
But it doesn’t
I think it's useful to adjust results for quality of opposition, but I wonder about how useful this particular method is.

Suppose you have two players, Player A and Player B, who each played 10 matches. Player A played 10 matches against world number 1, and Player B played 10 matches against world number 20. Let's say Player A beat world number 1 8/10 times, and Player B beat world number 20 10/10 times. So we have:

Player A: 80 - 1 = 79
Player B: 100 - 20 = 80

But pretty clearly, beating the best player in the world 80 percent of the time is more impressive than beating world number 20 every time.

The issue is that playing ability as a function of ranking isn't linear (e.g., the distance between #1 and #10 is wider than the distance between #10 and #20), so perhaps subtracting average ranking doesn't appropriately account for that nonlinearity. Maybe it would be more informative to compute an adjusted score for each match that weights opponent ranking (or Elo rating, whichever seems better).
Here’s the answer

Ok,but that's not true at all. In MMA Jon Jones had much more trouble versus lower ranked opponents, this is what happens in all sports. Conor had the most trouble with Nate Diaz who is ranked lower. So your premise is just wrong. And Djokovic having most trouble with Wawrinka destroys your argument that it's always easier to beat lower ranked players.

The norm is that higher ranked players are tougher to beat. To be objective we have to follow the norm.

Conor had trouble with Nate Diaz because he is in a different weight class, btw. Don't know about Jon Jones, he's unbeaten.
 
Lol

Another day in r/badstatistics
Also, how the hell do rankings in his mind prove your level of play? Roddick had higher level of play than Laver, but Laver was ranked higher. And also highest level of play also doesn't prove you are greater, again Roddick vs Laver.
 
This is excellent. You are onto something. Try with ELO also. Contact UST and discuss with them about refinement. This could end up as a official ATP statistics.

I think it's a great idea, it could result in @Lew II being busy for a while, so there will be less of his posts proving Djokovic is GOAT on this forum.

But Federer wasn't ranked nr.1 after 2010, that's the thing, so was he easier to beat? So, was Federer harder to beat in 2006? You said it, higher ranked players are harder to beat.

@Lew II if I go to the supermarket today, buy 2kg of potatoes, and drive the car back through the city at an average speed to 30km/h, do you think Djokovic would be the GOAT by this metric?

Still can't believe how good is Djokovic o_O
 
Djokovic needs more energy to win mathces. Which car more efficient? The one with less gas mileage. So, Federer is more efficient, means better.

it depends,
if you like red cars -> there will be a different answer
if you like electric cars -> there will be a different answer

if you like Djokovic, then no matter of the question the answer will always be Djokovic is GOAT

Not the case, majority of Djokovic fans don't actually think he is the goat, so does this mean some people can use logic over emotions? Who knew?
