Jurek,
I love your design, it's fantastic. As the booster weight moves further along the sling during release, it reduces the secondary sling radius, which in turn should accelerate the glande even more.
I haven't done the math, but it seems to me like the timing of the two releases would depend not just on sling lengths, but also on the ratio of the booster mass to the pouch+glande mass. It would be great if, for a known booster mass, the sling would have a series of markings such that for any given glande mass you could use a marking to compensate for the mass effects.
Reading this before work, I don't have time to build such a sling right now. But I did find an old toy, astrojax, to experiment with. It turns out the astrojax is a poor sling model. But it did give me this idea, which some creative slinger might incorporate somehow:
In the diagram below, string is black, rigid sticks are red. The booster weight, blue, would be a flared tube just wide enough for one string and one stick. As the booster weight slides down the retention cord, it also slides down the rigid release tip, until the tip is released. Another stick, or a large knot, can prevent the booster weight from sliding all the way to the pouch.
