@Slava Savitsky One of the points indicates "Because scripts are evaluated dynamically, including scripts in user criteria records can decrease performance.".  Is there another way you would recommend?

And for this point "Do not use gs.getUser() or other session APIs since they cause conflict when used in diagnostic tools. Use the pre-defined user_id variable available in the script to get the user id of the user being used to evaluate the script." have you scripted this way for user criteria?
