thanks for your input @JIMBOFMCD.
In the development process, the closer we get to data deadlock, the less manoeuvrability there is in terms of what data we amend. It depends on factors such as whether it is something that has brought to our attention, how important it is, whether it could have any undesired knock-on effects, and whether it can be done. We have processed 12m data changes since the winter update. The data is constantly changing, reflecting changes in the world of football. In the last few weeks we cannot possibly process everything that everybody wants to be done, or is asking to be done.
None of our decision making is based on bias towards either increasing or decreasing attribute ratings. @NickOGS20 is on top of the research, and is always ready to talk about any aspect of the data. The last Maguire/Sancho changes that you quote were made three weeks ago. We had to lock the data for the Early Access Beta some time before it was released, and immediately we were already working on changes to be made for the Full Release version of FM2023 (but again, the scope for the possible amount of changes was still more limited).
I think that Nick has explained Garnacho's ratings. I am sorry that you find that those ratings are not as up to date as you would wish them to be, but please feel free to use the editor to adjust his profile to your satisfaction.
