Hybrid stats

For ζ = Fn, Fs and [Fn - Fs], we plan (to be able) to take

  • the totals: ∑ ζ, ∑ ζ dV and ∑ ζ dm.
  • maximum and minimum with grid locations
  • ∑ ζ2 (primarily for ζ = [Fn - Fs])



And we want stats for fields we aren't overwriting, e.g. we'd like to measure how successful locking for ρ is when we aren't overwriting ρ.
