So my request is:
Could anyone calculate, example how many minutes would 12 or 24 SCVs/Probes/Drones have to mine to get over 400 minerals (in this case the cost of nexus or command center). Lets assume that these workers were transferred from another mineral spot to make things abit easier with the calculating.
I know workers have different mining speeds, and of course, I would grateful if someone could do calculations on every race, but one will do.

Happy calculating!
