Follow-up to what I've seen in the data: is the accelerometer over the center of the platform, or is it more "forward" (i.e. the direction where you punch out) in the platform?
My guess is that it's more forward, and this causes certain hits to be felt stronger. If so, it might be helpful to have two accelerometers, one in front of and one behind the center of the platform to detect different bag-platform hits.
My code is at https://github.com/neimet/SparkfunSpeedBag
It gets all four of the known sets correct and predicts 172 hits for Mystery Data 1 and 156 hits for Mystery Data 2. I didn't run it on an arduino, but I made sure it compiles and ran a slightly modified version (so I can actually run it) as a c program.
Here's the plot it produces for the 77 hits data set.
No public wish lists :(
