i think the reason it's not tangent is that the direction of curvature of boundary edge changes abruptly. (the trim curve which is the projection of a curvature continues curve (sketch 16) isn't curvature continues)

by the way, have you tried to model this up? do you have any process that may give better result. I'd really be interested in seeing other methods. Thanks!
Josh M
Yeah, I made the mistake of trimming with a combo of splines and lines there. I had tried creating the radius area as a boundary surface, then using a surface fill up to the top, but was getting even worse inconsistencies at the constant section. This definitely needs some more work. Thanks for looking over it... with a fine tooth comb (har har, ahy. :)

Thanks for this interesting model, mark and josh.
i wonder why boundary conditions are not actually G2 (not Even tangent, according to deviation analysis and zebra stripes), although they are set to be G2 in boundary surface options.

Thanks again.

Solidworm,
I'm not seeing what you've shown in your screenshot. See screen shot of my model here:

.02 degrees is within the tolerance deemed tangent.

I'll have to give this one to Mark or someone that know something about how SolidWorks is interpreting boundary conditions. Everything version I tried using boundary edges set to G1 (tangent) or G2 (curvature) would give me inconsistencies. Three things made the difference. Using 'Up to Edge' setting. Using more guide paths. Using Tangent instead of curvature.
After all the versions I did, I'm still try to create a model that is one continuous surface instead of cut and pieced together. Hope to have something soon.
