With a baro-only altimeter, you're not going to get very good speed and acceleration data no matter what you do. The baro is noisy enough that I end up smoothing it a ton before differentiating, which is why the speed and accel data look like they do. I played with a bunch of different smoothing amounts, and maybe ended up doing too much. Hrm. I could probably provide a knob in the 'configure graph' window for how much smoothing the filtered results got; that might be fun to see. The altitude data is coming directly from the baro sensor, so it's solid, I'm afraid. No filtering at all. -- -keith
