OK huge update here.
CL is correct, or at least it agrees with LTSpice AFAICT. R_s does not change the res. freq. So phooey on me, not circuitlab!! I don't know what I was doing before in CL, but starting over I'm unable to reproduce the behavior I saw quite clearly.
First image is the circuit.
Second/Third is 1k vs 2k2 values of R_s in CL/LT.
Fourth image is (CL) 500r R_s and stepping through the inductor DCR as 20r, 40r, 80r. 3 things to notice on this busy graph. 1) Resonance points move, 2) I resonance does not align with V resonance, 3) V resonance does not move in the same direction with DCR -- rather the V resonant point moves one way then the other, as DCR increases.
Fifth image is the same as #4 but with just 80r DCR, to make clear the shift between I and V resonance.
Sixth image is the same as #4 but in LTSpice. Note that the DCR here is "explicit", not lumped. I added a resistor representing DCR and stepped that, leaving DCR of the inductor itself at 0. I couldn't figure out how to step a "sub" parameter of a component in spice. Whereas in CL I'm stepping the DCR parameter of the lumped inductor.
So, first of all, seeing that resonance didn't move with R_s really cleared up a lot for me, this is what I expected and I must have wasted 30 hours after some botched work in CL where I saw it was moving.
Then, seeing that resonance does move as DCR changes reinforced more of my understanding. But the difference between I and V points took some more thought.
How can it be that I and V points don't align, doesn't this violate V=IR? [spoiler alert] I think the answer is that when XC = XL (resonant point), if these were ideal components the net phase would be 0 (+90L and -90C). But now that I've added DCR, I've altered the phase relationship. I don't quite understand this relationship, but well enough to intuit that adding a similar series resistance to the capacitor, ie ESR, will shift the net phase back to 0 and the I and V points should align. And they do! Image 7.
I know I've lost you all this far down, but now I have a vital question. Which is the actual resonance point, the minimum I or the maximum V?
