My own opinion is that when you finish with the 3 day training session you think you know it until you actually sit down and start using it. The training will be good for you to learn the features, etc. The best way to really learn it is by digging deep and playing around with it. Also are there any other expert users where you work that do not mine sharing P3 tips? This will be helpful also. Also, try to secure a copy of the P3 user manual and refernce manual.
