A Newbie is a Newbie
I'd use the blind in the off-season. Especially with the season over. You're a newbie, but you should not have any built-in prejudice about what works and doesn't work. Find out yourself what natural camouflaging works and doesn't work. Pretend you're in the military. Don't just depend on one site, if you can actually use more than one site.
If archery hunting, use the stool you are using, outside the tent and practice your shooting technique. After that, see what is different about shooting inside the tent. The best basketball shooters I knew, practiced the most outside of a game.
Practicing in off season isn't a waste of time. If you don't, only during hunting will your time be a waste of time.
