“another way is to use expressions to do the overshoot… First you’d key frame the scale from 0% to 100% (or whatever values you need) over several frames. Then enable expressions for scale (select property, then choose animation>add expression…) and then add the expression. You’ll find a good one here:

I used it and it quite nice but how can we pop it down with the same frequency. thanks
