The more powerful the plasma cutter (and the higher velocity of airflow, meaning a compressor that can keep up), the fewer issues with stack cutting.

I'm still not a fan. I far prefer to make a template for the cut, and make individual repeats. Far less grinding, less distortion, and actually less work overall, especially of you need to make 50, as opposed to three.

With a good quality template, you can make repeat cuts assembly-line style and have very little dressing to do to each part.
