@sportman/Darek could you test it on GDCC public test set file (test 1,2,3,4) please ?

@suryakandau@yahoo.co.id
May I know WHY you posted new version in a separate thread AGAIN? If it´s an upgrade (new features, tweaked code etc.) IT WOULD BE FAR BETTER to have only one thread - Jan Ondrus started it.
If you are disagree with my statement, consider an extreme case - we decided to make new thread for every new paq8px version. Result? Complicated navigation through many irrelevant threads.
So please stop that, otherwise I report you to Shelwien.

I agree with you but how about jan ondrus ? does he agree if i make some improvement on it ?

@suryakandau:
Don't mind him. In your case its better to make new threads.
Or even better if you'd just use one thread for all of your clones of codecs.

@CompressMaster:
Do you really want *sk versions in main threads of these codecs?

I don't know which the exactly copyright year of this. Is it 2008 or 2018 ? I have written Matt Mahoney as a credit for him

You put the current copyright year. See paq8px and paq8pxd.

Thanks. May I ask why you don't use a Source Control repository? Something like GitHub or Gitlab can be really convenient. We do this with paq8px and @kaitz does it with paq8pxd and paq8pxv.

Thanx for your input. I will try it

Hm...Compresses 0.4% stronger and 65% slower (compared to fp8v6). Good!

maybe this is the trade of between compression ratio and speed.

Of course! But if you compress it +0.5% stronger it will be the level of paq8pxd (default type).

Please don't post these in GDC discussion thread - its for contest discussion, not for benchmarks.
Also fp8 doesn't seem fast enough even for the slowest category anyway, it has to be more than twice faster to fit.
