If that's the case (I'm assuming that's a hypothesis, not a data driven conclusion), then what I said before is too conservative, & 'summer' recessive rebloom would be anything that reblooms less than 5 months after spring bloom.

Peak reliable TB bloom here is usually around last week of April , first week of May. 5 months from then would be end of Sept/early October. (if I did that right).
So anything blooming earlier than that (by the 5 month rule) couldn't be preferential rebloom. Right? 

If that's not right, then I'm missing something in what you've been saying.
That timing (end of Sept/early October) coincides with a bunch of rebloomers here that are normally reblooming earlier than what I think of as the 'real' fall cycle rebloomers.
There are two crosses in particular that I can't make sense of - IMM X Matrix. Imm is recessive summer, but apparently Matrix isn't - Imm X Matrix gave one out of a decent number of strong seedlings that reblooms & it's a reliable cycle rebloomer, starting late Oct/Nov.
Matrix often reblooms starting in September, but not in summer, and I don't remember anybody reporting summer bloom on it (which, of course, does'nt mean it doesn't have the genes for it).
But Matrix crossed with Tea Leaves has given at least one reliable summer (starting as early as August) rebloomer (it's an old cross, only have that one seedling, haven't tried to dig out notes to see how many seeds etc). 

Tea Leaves can start blooming in August in a good year.
Matrix pollen on one of the Imm X Csong kids gave at least one seedling that can start blooming in August (pretty sure few seeds from that pod).
And Tea Leaves pollen on a different Imm X Csong kid gave all August rebloomers.
So either Tea Leaves is a preferential rebloomer that takes less than 5 months to start blooming <or> it's a summer (recessive) rebloomer.
Either way, the phenotype early fall rebloom which it seems to pass to children.
Imm X (Final Episode x (Tea Leaves x Matrix) has three seedlings old enough to rebloom this year - two rebloomed - one rebloomed in July, Sept, Oct; the other in Oct.
The pollen parent has not rebloomed; one sib out of many rhizomes tried to bloom in Nov this year (first time any have tried to rebloom). So my best guess from all this is that 
Imm is summer/recessive
the pollen seedling is probably half summer/recessive
Tea Leaves X Matrix is probably summer/recessive
Matrix is probably half summer/recessive
I can hardly wait till next year - will really make an effort to irrigate & fertilize or find somebody to hire to do it.
