The math involved is likely to be extremely complex as there's a lot of constraints and variables involved.

Also there is probably no exact solution that will give the same spacing as there is on the cylinder part, so it's more of an "error minimization" type thing, and the actual things that you would probably want to minimize would be the distance between some circles measured from points on the perimeter of each circle, which is different than just distances between points on the sphere.

So the whole thing taken together trying to specify with a formula is going to be quite difficult.

Such things won't usually be solved by a single formula, it's more likely that an automated process would solve it by an iterative method where the circle for each hole would be adjusted slightly towards its neighbors and then that process repeated many times in order to distribute things.

Without some sophisticated iterative solver mechanism like that you can instead use your judgment for placing the profiles where you think they look good.

Now that you have seen the technique used for that particular construction, you can adjust those steps to your liking, you could change the amount of profiles, or rotate them around individually if you want to try some other kind of spacing.
