Combine those two theories at will...
Based on your build - Basically replace "level up" with "as your bars go up" in the above theories
My personal opinion, though only partially grounded in evidence is...
As you level up, more and more stuff becomes available. You start with ALL of the out of position SAs, and as you level up slowly 2% turns into 3% into 5%, +1 into +2 into +3, and more and more SAs become available along your tree. My theory extends to say that things don't become more LIKELY, simply become POSSIBLE. So as you unlock more and more, you'll still get all the junk, but some of the good stuff is possible, too.
My evidence/opinions stem from
1) This is much, much easier to code than shifting %s away from low and toward high. It simply allows Bort to add to your item list, and randomly draw from them with a few restrictions like no two SAs together, etc.
2) When you start out, you get out of position SAs like crazy, but then start seeing them less and less. This is evidence of the group of items possible growing, not the items themselves becoming less likely relative to others.
3) Building my o-line, I'll find basically only run block / pass block / get low early on. Then cut block, shock block start to show up, then finally protect and pancake etc.
What my theory lends itself to is
1) wait until you are level 30+ (this is when I start to see the last SAs and +3s)
2) if you want an out of position piece, FIND IT EARLY. Chances are, it will come with nothing attached. But that could be better than waiting 2 seasons to get it down the road when your rolls will be stuffed with crap you don't care about.
For example, rolling for my FB at level 7 I got first step, first step, route run, dive for yards, return specialist ALL THE TIME but never anything in the tree. They were basically all blank, sometimes +1, and I said what the hell I'll pick up two first step.
Great Post, added to my sooper secret Octowned archive.
