We press a ton of DTF, sometimes just laying the shirt on and pressing say the front and back together doesn't work as well for us. So threading the shirt on the platen or pillow, makes it the correct heat.
But there are different factors in every shop.

Yes, it's absolutely a thing. Over flashing can lead to what look like white dots in your print. they only show up after the oven, or even when you pull your shirts.

As far as ink failure on top colors, you'll ruin the shirt long before you see any issues there.
The only time over-flashing is an issue can be on some high polyester items, as excess heat exacerbates dye migration. But that is easily solved with any decent ink.

The old Riley Hopkings Swing away flash is the way to go. Some had forced air I believe. You could set time, temp etc. and it would simply swing out of your way and back in. Foot pedals on some, others had a mechanical motion detector. IR at the time so it was always on at the set temp.
Someone probably makes something similar but yes, shell out the dough.

Although the "permanent" pillow underneath would help to equalize pressure due to uneven thickness of seams and such, it isn't nearly as effective in reducing the pressure marks they cause.
Does the pillow inside the shirt reduce that? Or is there another method? It does seem the press marks from from the shape of the pallet, and not the heating panel. I need to look at my press again, but the pallet has more rounded corners compared to the heat panel itself, and that is what I am seeing on the shirts, the more rounded corners. So that tells me they are coming from the pallet and not the panel.

Laid flat with a teflon pillow inside?
What Frog says, use a teflon pillow inside the smaller shirts if having issues. Also get a teflon sheet for the bottom platen, this way the shirt slides on way more easily.
Your pillow suggestion gave me an idea. I have never tried the pillows before, but they sound interesting. Then I thought, what if I just lay the pillow down first, and then the shirt laid flat on top, that way I do not have to mess with putting the pillow in the shirt at all. So basically just leaving the pillow as the cushion for the bottom pallet, essentially replacing the foam rubber that comes attached to the pallet. Then I got to thinking, well since I already have the pallet wrapped in one of those teflon wraps, why not put the pillow under that wrap, allowing it to trap the pillow between the pallet and the wrap. Which would hold the pillow in place. Again essentially just replacing the pallet top with the pillow. This has me pretty excited! I am easily entertained I know. Then I thought, since I already have the telfon wrap for the pallet, why even buy a teflon wrapped pillow just to trap it. Why not just source a sheet of high temp foam and trap it under there. I could buy a sheet that hangs off the edges of the stock pallet by a 1/2" on all sides, which would eliminate any hard edges of the pallet. Time to start sourcing high temp foam! Thoughts on this?

Just in my head..
For me there was no set " time" . Different types apparel react differently to the flash. Also when I started I did not have heat in my shop. So it ewas different in the winter than the summer. You do one or 2 shirts of an order and that was it. No overthinking.
And yes one time, one time we had a customer bring back shirts because the top colors washed off the underbase. Someone one we were training did it on their first order. I can not say If it was over flashing, but it happened.
Understood. Sounds like I need to just get over the whole "every shirt must have an identical flash time", and just let the pallets spin as I work. Thanks for the input.

Could you use one of their smaller "tables" to swap out for the smaller shirts to eliminate the "stretching"?
DKP-1012TBL or DKP-1416TBL
https://www.heatpress.com/products/dk-10-x-12-table-all-thread-style
Looks like they offer a number of optional "tables" on their web site that are compatible with the DK20S
I considered that, but that doesn't help when I am pressing a 20" long print on a size Small. I am considering ordering a new 16"x20" pallet and modifying it. Laid flat with a teflon pillow inside?
Teflon pillow inside the shirt?
Im talking about loading a shirt onto the "pallet" of the press. Heat press MFGs call the pallets "tables". I do have a teflon wrap on the top heater part of the press, and one on the table as well (overkill maybe but nothing ever sticks), but I do not put anything in the shirt itself, well other than the cushion of the table. Does that make sense?
Here is a link to a video of the loading of a shirt. This is what I am talking about. They must have used a size L or XL for this demonstration. Would love to see them show us a size S and load it, cuz it will stretch. Scroll to the 2:20 mark for the loading or "threading" of the shirt.

I know I can lay the shirt flat, both front and back layers, but then the layer I am not pressing gets press marks too. I am trying to eliminate the marks on both sides of the shirt, wanting to press just the side with the print (say front only).
What Frog says, use a teflon pillow inside the smaller shirts if having issues. Also get a teflon sheet for the bottom platen, this way the shirt slides on way more easily.
I have a MEM Double heat press (2 of them) with a pedal. We have youth platens for it, but have never used them. We have had no issues.
I have teflon wraps on top and bottom, so im covered. And yes that def helps slide garments on and off, but does not help with the stretching. I guess I will look into the pillow, but that sounds like it adds a lot of time to each press, having to insert and pull out for every shirt. Sounds like the MEM press has a better pallet mounting setup, that doesn't stretch the tees. Wish Geo Knight would address this because it is such a simple design fix.
