First of all, you aren't entitled to anything in this thread. If you want to come and discredit my work then I'd expect you'd at least make an effort to back your claims somehow.
But seeing as you've not even bothered with anything else than whataboutism, I've decided to humor you. I took a look at the first file in the download you've endorsed.
I'll use some high profile players as examples since they should be easiest in terms of research to get reasonably correct.
Case 1: Eduardo (Kawasaki Frontale):
Set attributes amount to a recommended current ability value of 85, no weak foot rating given which means it's randomized on game start. Positioning has been rated 4, which is an outrageously low rating for a centre back at this level even if they were positionally suspect.
Case 2: Gen Shoji (Kashima Antlers) and Kengo Nakamura (Kawasaki Frontale)
Nakamura is one of the finest technicians and playmakers in the league, while Shoji is an excellent stopper-type defender with an okay pass and forgettable ability on the ball. Still, the attribute balance inside the league in this file considers Shoji to have a narrowly better natural technique than Nakamura, when the difference should be considerably in Nakamura's advantage. This is not to say there are no centre backs with great ability on the ball, they are especially prevalent in today's game, but Shoji is no ball-playing defender while Nakamura among in the ten best J.League players in terms of technique.
Case 3: Takuji Yonemoto (FC Tokyo)
Yonemoto is a player with excellent ball-winning ability and reading of the game. This player type would be aptly represented with high aggression, anticipation, tackling and work rate attributes but here it seems he's been turned into something of a box-to-box midfielder who slightly prefers to stand off instead of getting involved.
Case 4: Masato Morishige (FC Tokyo)
Morishige is one of the most complete defenders in J.League and very positionally sound, yet these attributes present him as something akin to an offensive-oriented full back. Apparently his height and weight are also some way off the real figures.
Case 5: Shusaku Nishikawa
No physical attributes entered here for a national team goalkeeper and long-time J1 regular.
I do not mean to put down anyone else's work but the aforementioned examples are objective (and, at times, grave) errors concerning single attributes, attribute balance or representing player types which to my mind do not endorse a very high level of detail. It is understandable as files like these are worked on authors' free time, but considering I've poured two years into this project focusing on the quality of research I can confidently say my work does not contain comparable inaccuracies and as such cannot idly stand by as someone has the gall to dismiss my work with baseless accusations. And if you spent more time reading yourself, you'd have realized that the second post in this thread mentions that the file is not a stable release and that naturally includes caveats such as duplicates or missing players as a result of the importing process from the previous year's version.
