How about we have a little laugh ?

In 2025, there is only one TD left who is still testing the EXP files with a concurrency > 1

I remember when you tested higher concurrency than 1, then learning "went backwards". Halfway through training you switched to concurrency = 1, learning went up, but the damage caused by concurrency > 1 did its job.

This one ?

[rulleeeee]

Ah, I confused multipv with convergence... But I remember that you proved that concurrency greater than 1 "destroys" the experience file.

...have you noticed a big difference between Depth4 Exp lines and Depth4 2025 after playing for a while?...

source

...My created Depth4 2025 is a BIN book (not Exp)!...
...so it will be madness, if its lines to be 100% same as EXP!...

...Since NNUE 2020, that means just a few years, someones started to use: Balanced / Unbalanced opening lines..
but before 2020 year, there was No such tern...

...I have no much idea about the differences But my 6th strong sense says that They should be close to each other...

But this Sedat's sixth sense has severe malfunctions :

ERROR MARGIN : 36% !!

Yet you had already been warned about this problem

...About your warnings, Listen, you're so new in my eyes...

ERROR MARGIN : 52% !!!

I will create a book, which will be tuned to prefer Depth4 Exp Series, played in latest months of 2025!

@To Deeds

Wow )) not bad 'search' by you ) but still not enough...since
I was referring about who are experienced in our Computer
Chess, such as by well-known testers who are from CCC, CCRL,
CEGT, CEDR, CSVN, FCP, FGRL, SPCC, SSDF, TCEC, TCERL, TOMs
Or other individuals TDs such as by Mehmet, Adam, Engeria,
Ipman, Jorge, RWBC, Sedat Canbaz, Sekos, Troid, Utzinger etc.
In other words, I never noticed that they used unbalanced term! sure
I mean before NNUE 2020..even if they used this term..not important..
But as most important thing is that, in case of unbalanced openings,
Almost all wins when via Whites.. understand ?) if still not clear ?
Chess is a game for 2 sides, at least it's so in my area where I live!

One thing more,
I am not going to share all Book Experts, because I may miss...
But just in case, the list will be full with Book Authors.. who
Never used to say: 'unbalanced' term, sure before NNUE 2020!

Btw, who knows? if you will continue to search, you may find,
Even who used during 1980s the unbalanced term) but anyhow
There is one true: Unbalanced / Balanced term became popular,
And it's started often used since NNUE 2020 for sure! However,
You will never know all about, since you was not active in past!

Hope helps )
