symptom | Measured head to head from one 63,840 byte buffer: adding 7.4 percentage points of drain multiplier (0.8991 to 0.9727) multiplied survival by 3.72 times, while doubling the buffer multiplied it by 2.19 and doubling again by 1.95. Survival is exactly linear in depth (R-squared 0.99941 across a 16-fold sweep) and hyperbolic in margin. |
