The most important piece of information on that document:
"This document was last modified on 17th Sep 96"
Yes, it was correct. Now, it isn't.

Ian,
As usual, the discussion is already taking place in another thread...
This is the nature of discussion.

I think
2100=180
2150=190
2200=200
2250=207.5
2300=215
2100=180
2150=190
2200=200
2250=207.5
2300=215

ECF * 8 + 650 = EloIan Lamb wrote:ok anybody got a new conversion link then please ?
ECF -> Elo
100 -> 1450
120 -> 1610
140 -> 1770
160 -> 1930
180 -> 2090
200 -> 2250
220 -> 2410
240 -> 2570
260 -> 2730
Given the formula, you can fill in the gaps.

There isn't an explanation on the website. It literally just has the formula and that's all.Richard Bates wrote: On what basis has the formula changed?

Re: this conversion right for new grades?
There should always be an 8*ECF in the formula because 25 ECF points is the same "should score 75%" as 200 Elo points.Richard Bates wrote:

The "traditional" +600 has been suspect for years, not as some believe because of deflation in the ECF system, but because of inflation/rating best results at the then foot of the international system.
Whether + 650 is correct, I don't know. It's probably about right at the 2100 mark anyway. At 175 the "red" grades are only about 5-10 points above the traditional grades. As a conversion for determining 4NCL board orders or seeding unrated players in rated events it's good enough.
