...Phew!...I finally got back to making a decent print of the control strip next to the reference. Look what happens to the control hd when I print for a neutral gray in the reference hd! Out of control man (nice color green though)! I'll show you a c.c.'ed print of the 2nd sheet of 4x5 that I developed at the same time as this strip in a sec....
weird c-41 control strip results in jobo

I laid a 40 magenta filter over the right hand step wedge. It then appeared to match the one on the right. Even the blue patch was corrected. This could mean only a color shift, not a contrast change.
It suggests that there is a color shift only, but I cannot prove it. You are seemingly doing everything right, but getting a cyan shift. That suggests underdevelopment somehow.
In any event, try taking some pictures of a step scale, as I suggested, and then printing it. If the scale goes from magenta through neutral to green, you have crossover. But, if you can balance it and get true color, then the situation is ok as far as I can tell.
Here is a sample of one I took and processed. It is Portra VC 160 shot at ISO 100 using an RZ67 in auto mode.

Here's an ra4 print of the first jobo developed 4x5 (portra 400nc on portra endura f paper). It printed at Y29, M40, 10" at f16. Same film developed at the lab usually prints around y55, m55. Nonetheless, the print managed to lay down on paper alright...
I'll do as you say, PE, and try the macbeth color chart.
I also just got in the 5 gallon flexicolor developer kit and the starter that goes w/ it just to see if it would give me significantly different results from the one gallon kit w/out starter. Should I mix the whole thing at once or would I be better off mixing just what I need and displacing the excess air in the stock kodak bottles w/ some nitrogen?

The picture looks ok to me.
IDK about the 5 gallon kit. I use the 1 gallon C41 developer.
I mix and store 1 gallon only from that 1 gallon kit, and store with a nitrogen blanket.
