Thanks for providing the comparison for me, Chuck. I don't know if I'm ever going to get this straight.
Could you explain a bit more what you mean by "maturity" vs "growing for an additional 5 months"? I'm confused about what you mean by a plant being mature if it has to grow for another 5 months. It takes ~6 weeks for a stalk to develop, if I remember correctly, so I see that's 1 1/2 months of the 5, but what kind of growing is the fan doing other than that, once it is mature?
Producing increases? Growing roots? Fattening up the rhizome? Seems like once it's "mature" and has bud set, it ought to be able to bloom in less than 2 months, not 5. Does the 5 allow for intermittent dormancy?
What am I missing? It sounds like Margie's rebloomers are having something closer to the 6 week turnaround (repeat bloom).
Also, if that's correct, then that would mean none of the rebloom I see is CA/OZ type, which means it's all either summer or fall cycle. And anything that blooms in July, Aug or Sept is either summer or has very high temperature thresholds for bud set and dormancy. The ones that bloom in July & Aug for zones north of here but not ever before Sept here presumably would have lower temperature thresholds for one or the other.
I can work with that theory. Just having to figure out whether rebloom is one or the other is certainly easier than sorting out 3 different possibilities.

Spring bloom,  then 2 months for  plants to mature, bud set and then
five months of growth. So  beginning of May bloom, so maturity of
increases  beginning of July . If get bud set temperature right away,
then five months later  would be January, with good growing weather and
no frost.

  In California flowering  in March.  Maturity of increases in May Five
months later is November.
