How to model this concave relief?

I'm new to OnShape and parametric CAD in general, so thanks for your help and patience.
As a learning exercise I am trying to model this physical object as accurately as I can.
What I have tried is to first create a loft to a point offset from the circle's center and then to slice the loft in half, and then remove half of the loft. It's not working very well for me. How should I go about modeling this feature?

Here's a couple of options.
blisters
a simple 180 deg revolve will get you close. But if your going for super accurate loft and or surface modeling may need to be tool of choice since it’s a punched deformation.
If you are working with Onshape Sheetmetal tool, this custom Feature should help: Sheet Metal Forming Tool (MBartlett)
One more option - model full dimple first, then sketch the punch profile, and "extrude remove" through the dimple. If you think about the tooling, and processes used to create the real part, this will give you clues as how to form the model. Good luck
Thanks for the input. I'll try these suggestions out!
