BUT, BUT, BUT!
I recommend you don't use the "Item Bonus" feature, as I've heard it's a bit bugged, additionally, you can't add attack speed % you'd get from swords, buffs or Blood Frenzy there.
If you want my advice, try to find a specific amount of attack speed you want to get. As an example, let's say you want to have 210 aspd with maxed blood frenzy (28% attack speed), with swords that each give 5% attack speed and Attack speed ring (5%).
That would mean, you'd need to have an X amount of base attack speed. Seeing as how Attack speed bonus stacks additively, you can calculate how much base attack speed you'd need for that simply.
(1+any attack speed bonuses written as a decimal value[100 times less than the percentage]) * x = the amount of desired attack speed, with 'x' being the amount of base attack speed you need.
Let's take the 210 example from above.
That would mean: (1+0.28+0.05+0.05+0.05) *x = 210.
A quick calculation leads to x being around 147 attack speed, if we keep putting Agi on the stat simulator with it being set to Crusader class, we get 66 Agi. Now substract the amount of agi your future equips will give you (let's say Eva chest equips), and voila, you get the base amount of agi that you need for a certain attack speed.
The same can be done with buffs (or other attack speed bonuses) to calculate how much agi you'd need for any attack speed.
But once again, remember that this isn't an official tool, and it was always be bugged in any way.
