DeRozan
Close Tendencies (L-C-R): 15-14-71 (= 100)
Mid Tendencies (L-LC-C-RC-R): 11-23-8-1-57 (= 100)
3pt Tendencies (L-LC-C-RC-R): 20-4-42-14-20 (= 100)

In 2K19 and 2K18 these WERE all over the place. Clearly there was a philosophical shift in how these are approached. With that said I am unsure why DeRozan (or ANY scoring wing) would have such a high Mid tendency from the right corner.

We all can all agree that this doesn't appear to be based on 2019 data, and as such is worth investigating further.

From what I can tell, the percentages that you see in each zone in a players shot chart are governed by the rating of a single zone divided by the sum of the ratings of all zones.

If you mean on the NBA site:
https://stats.nba.com/events/?flag=3...layer&sct=zone

DST = % of the player's FGA. For example 3.2% for DeRozan in the right corner means his 42 shots were 3.2% of all his FGs, not of his mid-range FGs.

317 Mid-range FGA for DeRozan
His Mid Tendencies SHOULD have equaled roughly:
9-24-30-24-13
but instead:
11-23-8-1-57

That said, the rating tendencies and the resulting shot chart of each player after simming a full season are no where near what happened in real life. Harden shoots most of his 3s from the top of line as opposed to the corners. If you look at his shot chart after a season of sim, 70 to 80% of his shots come from the right corner from deep. So if the data is translated into a rating to form the tendencies, then whoever at 2k did a real poor job of porting.

Can you elaborate further, as I am unclear what you mean by translating into a rating. I don't believe that is the case as I'm understanding it.

In real life I am a data analyst and I see this type of shoddy work all the time. It appears that there might have been a data the issue where the source has a different data type than what is accepted by the actual roster. Because of this, the shot location ratings for most of the players are not consistent and is resulting in skewed results as evident by the shot chart leaning heavily to just one or two zones. Whatever the cause, this is just terrible unit testing and QA control by 2k. In other words, no one bothered to test the data.

I can buy that.
