About it, i worked on the V7, but it was ended from July, with every transfers from Others America, stats updated from J-League PesMobile, shoes updated for every created teams and few corrections made (duplicates removed etc., but i noticed 3 new)
I'm was also done but some days later, a correction with every fake faces/errors corrections from South/North America, and Asia (also a tons of faces remade from players who were totally wrong)
For example in terms of data, South Africa have the record of the more players wrong i've found for a "licenced" teams. I mean big errors. Not Konami's fault : it's because there's a lot of player with very different data. But if you don't check pictures to compare... You will never be fixed if the player is OK or not.
Example of how i found those errors: That player is 198cm on PES and also on many websites. BUT he's also 179cm on others website:
https://www.pesmaster.com/t-hlatshwayo/pes-2020/player/104906/
So firstly, i check on soccerway (or other globalsportsarchive, footballinups etc. a tons of website) one game were the player was on the lineup, and with which number he played. Then i compare with others better known player on the teams, i mean players you can thrust.
HLASHWAYO is the Last UP/Right player from the team on the picture (i founded more but one is sufficient) :

Does he looks more 179 or 198 in your opinion? Well, He's smaller than some 180-182cm players, it's a game from 2018 against Paraguay at home if you want to check by yourself.
Now, for teams with very youth players registred (especially on fakes NT), it's about approximation.
I try to found two is possible, well known player which is with it at first. If i don't found it, i check on video an compare.
The level of approximation become less accurate but still better than for example 170cm 68kg for Asian typed players is the standard Hgt/weight, it's still better to have something closer, not only for representiation, but also for gameplay and physics. About weight, it's an estimation if he's more muscular, a bit fat, average, slimer or more stocky than average etc.
But it's more versatile. A player can take 10 kg in one year, especially youth player who goes to higher team and gets a training increased, or long time injured player.
I'm was doing the same as this forum without knowing it, same process :
https://www.foroalturas.com/f2-estatura-real-y-peso-real-de-futbolistas
When they "release" the real height/weight later on some website, my approximations are like 1 or 2 cm max difference, or equal.
I'm proud of it, i don't want to trow me flower, but that full time job deserves.... A full time job lol. I would like to postulate to Soccerway, or also Konami, and purpose that system.
And get the most accurate database ever made in any website or game.
Got everything on excel, but i miss some links to add for many players in European leagues i've done last year unfortunately. I don't want to share it right now, because firstly it's uncomplete, then it's a lot of research. It's a project to purpose for websites, but if i can, i will apply it for every teams on PES 2021.
The only issue is with DLC, they changes stats. And i got to recopy or reset every player modded. The changelog on PESDB is not very well made, you can't rank players teams it's automatically ranked by OVR, pretty annoying if you have changed 2000 players to make a manual research.
Right now, i'm focusing on Euro teams : it will be probably the most played mode. So i correct all mistakes.
Some teams i thinked to be hard to do wasn't that much (Faroe Islands) but it wasn't the case from the small teams like Gibraltar.
Liechsteintein wasn't hard to found errors, but faces were really bad. Faroe Islands aren't that bad, there's a lot of players from Sweden or Denmark leagues.
I also takes notes about real boots wearing lol.
Sorry if i'm of thread. Just wanted to explain. I rarely (well never) talk about it, as i'm very focused on it and not sure it will interest people but to me, height/weight and faces are pretty important in every aspect. Leagues and Football games should have more communication regarding data for more accuracy, or Fifpro (because it's "their" players) should build a website with accurate information, being more involved about them so some website or agency promotion wouldn't have the right to "increase" some of their player weight (i saw on youtube some player's promotions vids, with information given 188cm when they were 182 in reality or telling that their player are both footed lol)
)... its fun to play but in a different way. hard for me to explain in detail.
oh man.. i wish!!!
