## Group Number

Good name for the number of shots in a group?

The problem is thinking about targets (eg "Group number 4" meaning group on target 4).

The other thought was NSPG - number of shots per group

# $$\rho$$

The Greek symbol is used for the population value and letter r for sample value. Since we will use r for radius it seems prudent to just avoid using r and use $$\rho$$ for the sample value. Don't know if we need to get so detailed as to have both. If we do we could define $$\rho_{\infty}$$ as population value.
