How, exactly, did you come to the conclusion that 4 attacks at 75% damage is equivalent to 3 attacks at 100% damage? You're not taking into account the likelihood of criticals and the fact that you don't do the exact same amount of damage every time. Like I said, the most damage you could lose on a given attack is 4 (assuming a crit that gives 20 damage).
Also, since Flurry's damage loss only applies to base damage, your attacks are not hitting at 75%. Let's go with Moebius Death Blossom and assume that you're hitting for 7 damage with your dagger attacks. Also, let's go with 12 DM and 13 CS; you might not agree with those numbers, but they work for the sake of maintaining consistency.
Flurry, 7 dagger damage:
MS + DB = 125.75
No Flurry, 7 dagger damage:
MS + DB = 131
That is a difference of ~4%, or 5.25 damage.
Flurry, 20 dagger damage:
MS + DB = 155
No Flurry, 20 dagger damage:
MS + DB = 170
That is a difference of ~8.9%, or 15 damage.
Now consider that, due to your increased attack speed, you're going to get a free auto-attack in there in the same amount of time that it would take you to loop. If my auto-attack is a crit, I win. Even if it's not a critical, it's an extra attack. If I'm using vamp daggers, that's more health for me and more damage for my foe. If I'm using zealous daggers, that means I get more energy.
Of course, the difference is even more extreme when you start considering that maybe I'm running the typical BLS-TF-BSS-BoS spike. The 33% increased attack speed gives you a lot less time to get protected, kite, etc.
I'm going to be blunt: I don't think you're understanding IAS as well as you think you are. You have interesting theories, but I would strongly recmomend that you take them to the Isle of the Nameless, test them out on the various AL dummies, the Master of Damage, and see what kind of conclusions you come up with.
