Quoted from holminone:Getting my grammar police hat on. Seeing this more and more and getting to pet peeve status. Both the OP and here....
LOOSE is generally an adjective and means not tight. “The loose wire caused an intermittent short.” LOSE is a verb and essentially means to not win. “You lose.” Or “Bad pinball machines lose value faster than good machines.”
Loose as a verb might be “Loose cougars on the prowl attacking men at the barcade.” That might be both a verb and an adjective.

On topic, if someone really wanted to dive in I think the data are there, albeit imperfect. You could build a statistical model to predict the depreciation with variables that might affect long term price, such as manufacturer, number produced, code updates, etc.
If someone has a kid who's looking for math fair idea, I think that would actually be a great project.
