That's not the point as far as I am concerned. You think there is
selection of one SD critter over another based on temperature when you
store them in a fridge and/or "something else" may take over.
please look at those lines:

both are growth rates for a researched LB and yeast.
the LB has 0 growth rate at 4C - that's 40 F - I don't expect to grow
something below that temperature either
the yeas has 0 growth rate at 8 C - that's 48 F - I don't expect to grow
something below that temperature either
The fridge temperatures which have come up here are 35 F - below the 0
growth temperatures above.
I don't think you can have a selection/promotion of organisms by
temperature when nothing grows.
Your other point that "something else" grows in the fridge:
Why would "something else" grow at low temperature when "nothing else"
grows at decent growth temperatures outside the fridge and lots of germs
added with flour?
The deterrents - as I wrote before - don't just go away by cooling .
There may be a cooling period, where a starter put in the fridge starts
cooling down and some change of proportions may happen - who knows.
The effect of this will be factored in into your result when you do the
same routine over and over again - putting a ready starter into the
fridge, take it out, run it through the same stages and put a sample back.
What you are seeing in different behavior/results with your starter is
probably because you use a different routine and maybe have a more vital
starter with this.
In your initial answer post, you stated:

I still think that nothing much changes nor anything "fading" away in a
fridge storage of up to 2 month. And should there be a minor change
while cooling down - that's eliminated by factoring it into the routine.
If the germ counts are reduced by longer storage, it just will take
longer to get them back.
As long as both methods make good bread, who cares?
