Yes, I ground my own lamps...they are identical. What that question did bring to mind is, there is a.002 taper jam and a .001 taper lam in each limb. One is on one side of the wedge and the other is on the opposite side. If these were to be the other way around in one limb, I wonder if that would effect it???.
I had thought already about the straight edge on the limb pads thing. I noticed that when I traced out the riser that two straight edges do not meet in the center of the riser. They meet about 1/2" above center. My riser is the same.

To me it looks like left limb is a bit weaker in center.  I would measure out every 8" or so from end of riser each way and check limb width. If lams are accurate and correct tapers in both limbs, that may show up something. It don't take much width to throw it off...

The tapers being on top of or under wedge won't matter I don't believe. Its all glued together and should be same total thickness...
Stay sharp, Kenny.

Thanks guys,
Huh...I checked the limb thickness at the point where it looks weaker on the one limb. Turns out that it's about .012" thinner in that area as compared to the other limb. There must have been a lump of dust on the conveyor under that lam when I ground it??? Can't really think of another explanation for that. I usually check the thickness about every six inches when they are finished. Not this time lol.
Thanks again guys.
Kenny...I'll be in touch soon lol.take two...

Well I meant width, but thickness can throw things off too!
Stay sharp, Kenny.
