>> I do not know where you get your information. <<

I got my information from trying this on a few instruments and repeatedly checking what it's like after a certain amount "playing" (using the key), depending on how much play there was to begin with.

In all cases, putting an amount of teflon that is just right would have some play back pretty fast.
Putting slightly too much teflon so you can just feel a bit of friction, there was some play back after some time (not very fast but not that long either).
In some cases, I purposely put enough teflon to cause significant friction i.e. a little bit of resistance to the key movement. After some time there was free play again.

In addition teflon tape gets compressed and becomes pretty hard. It feels soft and squishy at first because of the air gaps, etc.

I thoroughly experimented with this method because I wanted to know how reliable it was if I wanted to use it. I use this method on rare occasions, but I don't consider it reliable to remove play, just a temporary fix, or when really removing the play is not so important. It absolutely can make a very loose key significantly less loose, but a little bit of play is usually not enough of a problem to bother with this (for reasons mentioned above) or I'd want to do what I consider a more reliable repair.
