Table 3. Fraction of the target area that must be actively transformed to produce about 80% (π/4) coverage in T generations.
| RI (area) | 40 generations | 30 generations | 20 generations | 10 generations |
|---|---|---|---|---|
| 400 m (0.5 km2) | 0.09-0.20 | 0.13-0.26 | 0.20-0.35 | 0.35-0.50 |
| 560 m (0.99 km2) | 0.13-0.27 | 0.18-0.33 | 0.27-0.43 | 0.43-0.57 |
These calculations assume wave speed c = 10-20 m/generation starting from initial releases in circles of radius RI that produce local infection frequencies p0 near 1.
