Which side of the bench?

Here is a different way of studying SCOTUS arguments--which side of the bench is most active in questioning and draws the most attorney attention? For right now, the answer seems to be to Chief's left/attorney's right--Alito, Kagan, Kavanaugh, and Jackson.

This is of limited long-term use (as opposed to looking at individual justices) because seating changes frequently. It might have been of interest with the long Breyer-juniormost Court (1994-2005). On the other hand, I would not be surprised to see the current Court remain for the next 7-10 years, so maybe that will give us a longer sample.
