Wow ! Excellent test! So, ... results? I saw the window on the right (the formulas solution) regenerating faster, in the progress bar, and at the end, in the view. Conclusions?
EDIT: But, by a nose! Not really a significant difference at the end. Very interesting test. I thought you were going to place 1,000 instances, but you put 10,000 instances of each family !
Now, how did you make this video? How could you click on two sessions at the same time?
