split circle into 8 equal pie pieces

Question

Hello. I have searched around on here, and was able to find some workflows that have helped me get this far. The issue I am having is that I can't split the circle into 8 perfect equal parts, since the 100 points created by the poly-split tool cannot be evenly divided by 8. Maybe there is another way to do this? Or maybe there is a way to have the poly-split tool split into 200 points instead of 100 points? I couldn't find any settings to change that.

Here, I get a result that is VERY close to what I need, but the odd numbered polygons are slightly smaller than the even numbered polys, so they aren't completely equal parts.

So close! Anyway, I appreciate any help! Thanks!

As discussed here, the earth is an ellipsoid and cannot be accurately divided into eight equal parts.

However, I think a closer approach is possible.
I've created a workflow to get closer to equality by adding the midpoint of each Pie shape.
I create only at small pie.

It may also be possible to get closer, but I don't know the way.

It might be easier to create the midpoint of all the points first. Sorry for not thinking about it.

I attached the sample WF, please find it.
