Delaying animation with expression controls instead of keyframes

Hello,
To get a slight delay in my animation on each duplicated groups, i made this simple expression on a trim path :

i=(thisProperty.propertyGroup(2).propertyGroup(1).propertyIndex)-1;
value + valueAtTime(time+i/10)

But i just want only one set of keyframes to control every groups.

if i replace the "value" by a slider control for example, the delay no longer works. I don't know why.

Any idea? Thanks

Why would you replace the "value" with the slider? This makes no sense. You need to manipulate the time inside the valueAtTime() function. Of course you may need a ton of extra code with linear() functions if you need exact values instead of the oens the function gives you, but I think you simply misunderstand the basics.

Because i want to duplicate the animation on a great amount of sub groups and be able to edit theire animation interpolation with 2 keyframes instead of hundreds. the linear doesn't give me this flexibility of editing though.

I think it will be something like this:

delay = .1;
n = thisProperty.propertyGroup(4).numProperties;
myIndex = thisProperty.propertyGroup(3).propertyIndex;
diff = n - myIndex;
myDelay = diff*delay;
s = effect("Slider Control")("Slider");
s.valueAtTime(time - myDelay)
