For roll control on the 320, max deflection is 35deg. Spoilers 2-5 I believe move equally.
For speedbrake function, they are deployed with different deflections.
I can't find anywhere at what aileron deflection the spoilers start to move, suffice to say they are not both at once. Its about a quarter to a third sidestick.
