chess.com ratings are deflated against USCF

Why does it matter if someone else locks it or not?  Does this topic being "open" somehow personally offend you or detract from the quality of your life in any way?

Lol, exactly what I was thinking.

I lost interest some time ago. Add 250, subtract 250, who gives a s--t. You are a blowhard asshole.

Quit trolling. If you don't care, leave! Why are you here? I'm here, because I started the thread... but you? Don't you have a life? I don't care what you think, I've stated that repeatedly... so why are you telling me? You don't like me? Do I care? No!

I have noticed AdamRinkleff has not once commented on the linear correlation that I keep bringing up. So either he has 'overlooked' it, or he finally understands that this is correct... linear correlations ("mx + c") are the most common

Either that, or you might just lack reading comprehension skills, because I did address this more than once. Meanwhile, you also lack some basic problem-solving ability.  I mean, really, if you wanted to use a y = mx + c equation, it shouldn't be hard for you to guess that if y is a USCF(standard) rating, and x is a chess.com(blitz rating), then c ~= -250 and m is approximately equal to 1.

Really, you sound silly insisting that there must be a y = mx + c equation... uh, dude, trust me, a precise formula is gonna be a -lot- more complicated than that.

Ultimately, I'm not interested in a precise formula which will exactly transpose a USCF rating into a chess.com rating. What, you think I want to write a dissertation on this? Lol! I'm merely interested in the very simple fact that the average difference for the average player, is about 250. That's good enough for me. Why are some of you being so obsessive and weird? Get a life, lol. The average difference is about 250, and you might as well stop denying it.

You could waste a year calculating the numbers, and you'll probably conclude that the average difference is 242.3867 or something. Good job!

If you don't like a thread, quit posting in it. Quit trolling. Quit arguing. Quit whining and saying how you hope the thread is locked. Grow up! Get a life! Go away. Talk to someone who wants to hear what you have to say. If what I've said doesn't make sense to  you, that doesn't mean I want to sit and explain it to you. Lol! I've got better things to do than teach you how to find an average.

You sampled the wrong population bro. it's definitely 250 points minus your blitz rating just look at people like Becky, Expertise, and I.  So since you are 1550 blitz it means you are 1300 uscf.   

Anyways....In B4 the Lock.

Grow up, bro.  Nobody (credibly) said anything about a lock.  And certainly nobody decided overnight to let you run the forums.  You dont like it?  Well, move on and go to another thread where you can kiss the mods asses all you want!

u mad?

deal w/it

Now I find myself in question
They point the finger at me again
Guilty by association
You point the finger at me again

I wanna run away
Never say goodbye
I wanna know the truth
Instead of wondering why
I wanna know the answers
No more lies
I wanna shut the door
And open up my mind

Always interesting to see how people often tend to focus on proving they are right and others are wrong! Tongue Out As opposed to objectively trying to exchange information and get closer to solutions and better answers to questions.

I think it would be interesting though to see a graph of uscf ratings, and other OTB ratings, compared to the various average chess.com live ratings.

AdamRinkleff just to summarise in 'baby language' which is easy for you to understand, the difference between the two rating systems is not a set number. It is not 250 nor Is it 242.3426. It is a continually changing number, not a fixed number.

Do you morons know what an 'average' is? As in, the average difference is about 250 -- I think I've said that ten times now. You people are such nerds. You are trying to prove I'm wrong by arguing how 'complex' a precise comparison would be. No kidding? However, an average is really a very simple concept, and the average difference is about 250. An average is good enough, and I can't imagine why you are so obsessive-compulsive.

There are several ways to measure "average". There are also ways to measure how closely the various data points correlate. One of the simplest tools is "standard deviation".

Here's a simple example:

Let's presume 5 players are rated 2000 USCF.

Let's pretend their chess.com blitz ratings are:

1750

2000

2250

1500

1250

The average of their rating difference from their USCF rating is 250 points. But it does not mean we could predict anything about the next 5 players' ratings based on that information.

Yah, write, I dropped a ball thirty times times, and the average acceleration remained consistent and almost exactly the same in every instance... I simply can't even begin to predict what the average acceleration of gravity might be... durrr. What a tool.

Of course there are standards for physics experiments as there are for calculating statistics.  But I think you know that already, and are just having some fun.

*** Top secret Formula***(Not really but what the heck)

Here is my top secret formula for calculating my exact ELO rating. 

First I use Equations from the Schrodinger equations and then by using only the valances of the electrons in my brain I calculate the variation of the orbits of all the Atoms located within the probability wave of my vicinity and by factoring in the Heisenberg uncertainty principle and subtracting my level of boy friend distraction I come up with my exact ELO rating. Unless its Sunday  morning in which case I subtract 14000 from my answer. 

Cheers, Becky

PS - I have to go now as im watching Star Trek and learning how to play a game of cards Called Fizbin. ( If you dont know what this means, your not as smart as you thought you where. )

The differentiation in the schrodinger equation is too annoying.  It's not even worth doing this estimation:D

Watch out for the table (unless it's Tuesday).

Because all people have to watch a show that is full of contradictions, meaningless gibberish, and weak episodic plots to qualify as smart.

Did you just take that post seriously? And out of all the other crap in this thread you decide that THIS is the straw that broke the camel's back...

I need a synthale...

I only took the part I quoted literally.

mrguy888

Well I know that now but I still don't think the part that I quoted makes very much sense.

Naaahhh. You're (Canadians please note) only smart when you can chant the dialogue (especially of the re-used sgments) and wriggle your ears in a suitably Spock like fashion.
