Can anyone explain why FL outbound numbers go up and down so much?

I still have yet to figure out what the deal is with FL and outbound rates with cars.

I'm central FL and I tend to do a 100 mile radius centered in Orlando. I'm a hotshot not a big rig. my typical search is min .70/mile with min pay of $500 or $800. (I use 2 searches the $500 is for basically next-day delivery runs. So a radius ending in the NC, TN, LA radius.) The second $800 up is for anything not SE regional.

What gets me is 2 months ago the $500 search was showing over 300 cars. The $800 about the same.. In fact, I'd usually run the price up to $700-800 for the regional or $1k for the long to find the best rates.

Last month it was down to the 150ish cars per search.. Today each search has about 30-50 cars for the same search.

Everything has been so screwed since the trade war, to coronavirus and now the chip shortage that I still haven't been able to sort out any rhyme or reason for the fluctuations in the outbound market. I understand when snowbirds are coming down the outbound market craters because too much capacity coming into the state looking to leave. It's the reverse when snowbirds leave.. Can't get a load into FL but pays well leaving but the prices seem to have been going up and going down repeatedly over the span of every few months but I see no real reason behind it. It's like for 2 months the prices are crazy then 2 months later they are absolutely crap then they spike again in a few months.. Is there any rhyme or reason to this?

It seems to me that the chip shortage should be driving prices up for outbound FL because it's a hotspot for dealers buying used cars. I don't get why the prices have dropped so much in the last 2 months with this shortage going on meanwhile fuel prices keep going up.
