Its the same idea, the "DOT" simply replaces the physical PIN that extended from the core to the surface of the ball. So when referencing your layout, just treat the "DOT" as if it was the PIN.
I think a lot of people don't realize that the pin on a ball is not just a marker, its a physical piece of material that extends from the weight block to the surface of the ball that is used for manufacturing purposes, while also indicating where the top of the LOW RG axis is on the ball. The pin creates voids in the ball in that area and this is typically why when you drill close to it, the pin can crack out, or the ball can end up cracking, because of the weakened structural integrity around that area.
The new "DOT" is still marking the top of the LOW RG axis, just like the pin did, but its only an engraving. It is what you will use for layout purposes for that middle number in a dual angle layout. The physical PIN used in manufacturing has been moved to the bottom of LOW RG axis and will not be needed for layout purposes.
The whole purpose is to not have to drill near the physical PIN anymore so that it is less likely to crack, which is particularly why they are offering a 4 year warranty on the ball.
