That looks good - thanks.
I think you might find these to be helpful:
PD20796 - Adopting Host Intrusion Prevention - Best Practices for quick success
PD20748 - Host Prevention 7.s Adaptive Mode
Or have you already looked at them ?
I downloaded the 1st one. The 2nd one was a bit too generic and high level. I was looking for a little more detail.
PD20748 documents the limitations of Host IPS Adaptive/Learn mode. I would recommend reading this guide as well to understand what Host IPS be learn and not learn, as you are tuning the policies.
