Multiple detriment jumping = too high self-damage

Edit: it seems that this happens with Juggernaut too. Two juggernauts right next to each other jumping together on top of two other juggernauts destroys most of themselves.

When multiple units (with jump damage) jump together and land on several other units, somehow the damage is MUCH higher than stated jump damage.

Jugglenauts did this for a long time so I'm not surprised. I suspect it is something to do with suddenly being inside another unit when impulse is applied, which makes the collision velocity look high. Someone could look into something like a velocity limit in the collision damage gadget, if this is the case? Or maybe leave it as an easter egg?
