Best technique for creating low profile rounded bumps on a curved surface

Hello,
I am designing a rounded cup with circular raised bumps with a low profile. Almost like a tiny hill on a rounded surface. I’m trying to find a solution that looks clean and will be easy to manipulate if changes need to be made. Thanks.

Here is my attempt. A Linear pattern then a Curve pattern. I am not sure the most economical as I do not pattern often. I used Conic in sketch of 'bump' for a more interesting shape.
Cup with bumps.

Here's a wacky little tool to do it with a FeatureScript. It will work on services that are relativity (but not perfectly) conic.
It will add bumps and optionally fillet them - (be careful to use proper sizes/angles/distances). It can obviously get pretty slow (so be patient).
You basically have to define an axis and starting point (mating connector) - and tell it to start and end a certian distance up this "shaft".

I've just tried this out, and the first bump added is getting created as a separate part.
To fix it, I just transposed lines 95 and 96, so that bn is being incremented after the union, rather than before.
