I need some schooling on my new A833!!!

Does it have the 18 spline input (main drive) shaft?
I believe all the "racing" ratios were designed around the Hemi/440 gears.
From your chart it looks like it would be a good choice for road course work.
The higher the gear ratio in second the better for certain lower speed corners.
To keep you from lugging the engine by shifting to third too early.
Its interesting that the chart doesn't mention most of the 23 spline units at all, other than O.D.
If it doesn't suit your combo. bet you could sell or trade it pretty easily.
