Optimize Scallop for good surface finish for foundry pattern tooling

Can anyone give suggestions on the best way to optimize a finish scallop operation (see attached example file) for good surface finishes?

I know the tool & die, investment tooling pattern makers, etc. must have some tricks to reduce the cycle time and still give some great surface finishes.

Using a bull nose with a 0.015-0.025 step over to give some good scallops on vertical walls that require draft angle, it seems that the scallop operation doesn't recognize when there is a large flat area so it takes along time to get those area's machined with that small step over.

 

Do you typically use the contour or only select the vertical walls for the scallop operation to speed it up?

 

Does anyone have any advice?

 

TIA,
