Question about official records?

[jeanpaul4289]

Yesterday i was checking the official averages and i notice that some details are
wrong for example the world record average if you calculate the average the result is not the same, now im confused, maybe i dont know how to calculate the average or my calculator is not working well:confused:

Did you subtract the fastest and slowest times from the average? The WCA uses the 'Real Average' formula which means they take your middle three solves and use those to determine your average.

ohhh thats why. i was thinking that they uses all the times.

Real? Would you expect it to be imaginary?
(And how is it more "real" than any other scheme?)
Also, fastest and slowest times are not subtracted, just dropped.

Anyhow, I just cite the Olympics for this...

If you're not sure, always check (9f8).

Hence the apostrophe marks... I believe that is what everyone calls the formula anyway. They say it is your 'real' average formula because it does not take into account your fastest and slowest times. If you take a look at the UWR board you will see that a few people use the abbreviation 'RA' for "Real Average."

Also, I mean to say drop but I could not find the right word at the time, lol. Brain freeze.

"Real" average ?!???

"RA" usually means Rolling Average.

Damn, I'm an idiot.

EDIT: lol, so that I don't look like a total idiot. I was actually told when I started cubing that that was what RA stood for. And someone was always using those words so I guess I've been brought up in cubing wrong, heh.

LOL. All this time I thought it stood for 'Record average.'

That has some true in it, for CCT at least because it only shows the best average of 10 you had that session

There's a reason we have a Cube Glossary, too. ;-)

You might want to double check and then if it is still wrong you might want to E-mail someone.
