Tactics and FIDE Rating

That other site - their rating system seems to converge too quickly. If you make an early error it seems to pigeonhole you. My rating after 100 trials is about 1935, with 72/100 correct. Seems to me it should boost the difficulty of the problems presented as you get them right more so than it does.
Just one point on this one: looking at your stats on “that other site” (assuming I picked the right user! 
), I think the reason you are not getting harder problems is because you are getting a number of the problems over 1900 wrong. You have 72/100 overall, but under 50% on those, and I think largely because your average time is under 60 seconds for these problems (vs the several minutes used by other users). If you want harder problems you could set the difficulty to hard, but this will not impact your rating too much. Best way would be to increase your accuracy on those, which will in turn result in higher rating problems being served to you (it will shift your bell curve to the right)
Hope this helps!

147 BCF x 5 + 1250 = 1985 FIDE.
The formula for converting BCF to FIDE:
When BCF < 216, then ELO = (BCF x 5) + 1250
When BCF ≥ 216, then ELO = (BCF x 8) + 600

This difference of about 300 points (1985 FIDE and 2300 TT) agrees with post #10.
"I believe the tactic trainer rating here at chess.com is much higher than a FIDE rating. Im 1700 fide rating, and about 2000 tactic trainer. Its the same with 3 of my friends, and my coach is about 2300 fide rating, and over 2500 tactic trainer." - Simon Seirup
Thanks for doing this for me.

My pleasure. :)
CONVERSION BETWEEN FIDE ELO, OTHER NATIONAL ELO RATINGS AND ECF GRADINGS ECF x 8 + 650 = FIDE
(FIDE - 650) / 8 = ECF
ECF x 8 + 600 = National Elo
(National Elo - 600) / 8 = ECF

You refer to '*.cpp', rather than ".cpp", oh villainous one ?
Not sure what you mean.
Edit: Oh, you're making a distinction between single quotes and double quotes. I was looking at your dropping of the '*' character.

And he was saying that you should do a very small number of new patterns per day, IIRC.

Yep. Didn't notice that the * had been eaten!

Where did you get that formula from? I thought it was FIDE=(BCF*8)+650
That's what I read too.

And what's BCF anyway? It's ECF now.
Well, if you don't know what BCF is, then how could you possibly know that it is now ECF. You're not making sense. 
BTW - I don't like that The British Open is now called The Open. It sounds to vague.

I think a lot of David Pruess's meaning has been lost in paraphrase. He never suggested blitzing though the problems.
What he recommended is that you spend a minute or so trying to solve the problem. If you can't solve the problem, then use the "show solution" option to work your way through the problem a couple of times, until you fully understand it. In this way, you incorporate the pattern and it becomes a part of your armory.
David isn't saying that you should blitz through the problems, but you shouldn't spend a huge amount of time on a single problem.
Thank you for the better wording. David is an IM, so I can't imagine him being completely wrong about something.
The psychological factor alone of hitting the solutions button and going over the missed pattern many times until it sticks...well...it was most liberating. I got through many, many patterns - and hit my highest score on tatics trainer ever.
I didn't get mad this time for getting some of the problems wrong, because I had something constructive to do afterwards. Go over the solution. Geez! I have to hear something more than once until I get it. Again, thanks.

:) It is chess.com's mistake, they have not changed it bcf to ecf, but it is ecf.
Found on google, interesting topic.
My chess.com TT rating is 2250 at the moment, chesstempo.com standard rating about 2050 and blitz 1700.
Does anyone know the relationship between chess.com tactics and otb ratings, I am 2300 chess.com tactics, but obviously far lower otb.
147 BCF x 5 + 1250 = 1985 FIDE.
