I'm with two-dogs and NaviDave, in that the venison does not age the same way beef does.
Not that it matters if you are freezing it anyway, where the ice crystals break down the cellular structure when that happens. Whole different game than taking an aged side of beef out of the cooler and making fine cuts out of it that are served without ever being frozen!
I was told by both a game biologist, and a trained butcher, that the enzymes that work their wonderful magic on a side of beef, are not present in Venison, and with the different structure of the deer musculature, as well as the different way they store fat, that you are essentially adding to the trim pile, the longer it hangs.
That's what I work on. Have hung deer for a week and more, and have had them into the freezer fast enough that they should have still been twitching, and have never noticed a difference. It'll be made, or ruined, by the cook.
