I really don't think people "get" what super elusive is yet or how it works.
I know Bort said you need 70 agility to make it work, but that is only so you don't get tackled for a loss every time. SE is about lateral movement or agility and not speed. When you run on SE, the script is always looking for lateral movement to throw off defenders first instead of creating separation. Always. That is why we see it bug out sometimes once a runner is in the open field. The script is still telling the HB to use that agility to make cuts that the defenders cant. I would say you need to have agility at 80 and more likely 90 for it to work without a lot of bugs, the more quick cut you have and first step the better also.
Really, the old elusive is governed by speed and the super elusive is on the opposite end and relies heavily on agility. I really don't know how else to make it more clear. I've been studying footage of backs with low and high agility, and the higher agility backs on super elusive are always faster. If you are running 5 yards sideways then you need that extra agility to allow yourself to boost to full speed faster to negate the sudden advantage the defense has with you running laterally and changing direction. It's a problem that we haven't seen before because of the way elusive worked before, more north-south so higher speed governed since the back was not fully stopping, slowing down much, or changing direction.High agility backs can also make those open field "bug" plays where they slow down and cut when it's 1 on 1 for a TD, the higher agility back simply is too good at cutting and the defender falls down. That is what SE is all about folks, not speed, agility. A moderate speed of in the 90's is enough with the boost in acceleration you get from the agility and cuts. It's what makes SE work.
My back isn't at 100 speed, but if you look at his replays I posted earlier in the thread, or even this one:
http://goallineblitz.com/game/replay.pl?game_id=376183&pbp_id=1803781You can see how much faster he is than backs with more speed running on SE. It's the same for all backs again that have a very high agility. You will know when SE is working in the game as you will see the defenders "bounce" as they are falling down because of the cuts.
