Over the years there has been ample examples of setting a value in a
datawindow using the setitem compared to the dotnotation, and so far the
research points to setitem and getitem as a winner when dealing with more
than 500 rows.

How does the comparison stand today using pb9,10,11,11.5?

I'm guessing it is because there is a casting of datatypes using dot
notation , where getitem and setitem are more strongly typed...
