I solved it with a iterative macro for the 1000 cases...inside another iterative macro for the 49 different sample sizes 🙂

to reach 75% we need 33 people

Good one, think that I'll be using Generate Rows more often now rather than brute force; very elegant.

Solved. My first time using a macro (and exporting a package)! 😃
