contact pattern

On used gearset, is it necessary? I know you need to test with new gears.
Some of you followed my chipped tooth on pinion thread and know I`m just replacing pinion bearings, well that solved the catchy part of that problem. I also installed the crush sleeve eliminator. Turns nice now with 19 in.lb. preload and .006 backlash.
I used prussian blue and see marking all the way across the teeth on drive and coast sides.
I reused the same pinion depth shim and hope this doggie will hunt?
Is this a normal pattern on used gears?
