Paper 62 of the Non-Holomorphic Fractal Series extends the single-probe revisit inequality derived in Paper 61 to an explicitly fleet-coupled form. Paper 61 established that the 10 m × 10 m × 1 m square high-density recirculating aquaculture system (RAS) tank operator lies outside the numerical killing zone on all tested finite grids (N ∈ 64, 128, 256, five drain configurations), confirming a geometric mixing penalty Dgeom = 1. 0 and a per-probe two-channel revisit bound of 3 min (dissolved oxygen, 300 kg/m³) and 10. 15 min (ammonia). That result is a necessary floor, not a deployment specification, because it silently assumes one mobile probe per tank. Paper 62 lifts the fleet size k to a first-class parameter, derives the fleet-coupled safe revisit regime Tᵣev^ (k) ≤ Tcritᶜh / (2 Dgeom) under the ideal staggered-phase assumption, and inverts it to obtain the minimum fleet size kₘin (ch, ρ, drain) = ⌈ Tcritᶜh (ρ) / (2 Dgeom Tₜarget) ⌉. On the executed grids, with a per-probe target of Tₜarget = 6 min, the ammonia channel forces kₘin = 2 across all five drain configurations and all three tested densities — consistent with the operating team's empirical requirement of 2–3 mobile sensor units per tank. The qualitative three-stage deployment picture (static-only baseline, dual instrumentation, reduced-static replacement) follows directly from the fleet-scaling inequality and is independent of any specific feasibility study. All numerical claims are finite-grid statements traceable to six locked CSV files supplied as supplementary data.
