1. They also publish for negative events. Look at the really low Z-scores: http://noosphere.princeton.edu/results.html Also you can get all their data (downloading it day by day).

2. Possibly, but unavoidable to get rid of a systematic error which would pollute everything else. Details are here: http://noosphere.princeton.edu/gcpdata.html

1. They publish events that don't have high scores, but they don't publish non-events that do have high scores.

2. I was actually wrong on the VN whitening, they use XOR, either 10 for some devices, or a 560 bit mask for others(!). This is just silly.

  the XOR is used to exclude an important class of potential spurious effects — biases that might arise from temperature changes, component aging, etc.

It's not excluding spurious effects, it's hiding it.
