Not to mention that each bounce has to strike a new target. Run out of targets, and regardless of whether the bounce could happen, it stops.
Has anyone run the math on both versions?
It's not wildly unbalanced or anything, it's just weird. Damage spells scale (at least all the ones I'm aware of, I haven't checked all of them) so that they do their highest average damage / spell level at their base level, and then the average drops.Your numbers are helpful - I hadn't realized how much the bounce chance increased with additional d8's. However, as Hemlock points out, that just means chaos bolt is not a horrible choice for upcasting. It's still not clearly superior to other options, and certainly not unbalanced.
Except that this version of chaos belt doesn't. Factoring in hit chance (I used 70%), it starts off doing 6.85 damage/spell level at 1st level, drops down to 5.5 dmg/sl at level 2, then scales up after that. Again, it isn't necessarily bad, but it's different, because adding a damage dice increases the damage of the base spell, the chance of the bounce, and the damage of the bounce. It's kind of like if scorching ray gave you an extra ray AND increased the damage of each ray.
Not a big deal, really, but something to keep in mind.
