Legend: top graph of each pair is motor speed V (i.e., edot), bottom is load. Top graph is the one to pay attention to. Translate V to edot thus: V0.05 ≈ 3e-8/s. Horizontal scale is time. 5000 pts ≈ 14 hrs. | ||

e not measurably different because of noise issue. | end of run, ~ 2 hrs later. (Note vertical scale change.) Looking back over these images, I see no significant change in edot since pt. # ~11000, which was 36 hrs ago. Mean is ~V0.015, or just about 1e-8/s. Sure looks borderline; let's see how 567 works out. |

e = 0.0279 | End step (1a), ~22 hrs after start. edot has fallen to ~5e-8/s. Sample immediately proceeded to spring a leak at the start of rebound measurements. Remove, take photo at top, rejacket, restart. Time lost ~24 hrs. |

e ≈ 0.025 at end | Start step (1a), 1/7/09. Sharp upwards step in middle is gear reducer change, from 10:1 to 100:1. V to edot conversion factor above applies after the change here, and to all the graphs above |
