Also as the Chronicler, you don't HAVE to call for obvious easy skill rolls.
I will typically only call for a skill roll from perception list if the target of the skill is actively rolling a skill to hide or deceive.
The person skilled in hiding or deceiving, as example, might be much better at doing so than the one initiating the perception skill roll is at spotting it. That's just tough. Put some of those free experience gain points in perception skills.
If there is NO target rolling against the initiator, such as a hidden door as example, I usually make it an easy Skill roll if tthey're actively searching.
