I believe your analysis is correct. No recount has changed that many votes.
Florida has a rock solid voting system that’s hard to manipulate
Remember the Gore recount was denied because they only wanted to do three heavy dem counties and the SCOTUS decided that would disenfranchise the rest of the state voters...
Now what left are the firing of snipes and the vote totals certified after the recount....which will not chang who won...
They only did 3 counties
