Narrative:
Aircraft was in level flight at 33;000 feet when the captain's side windshield shattered. Followed emergency/non-normal checklist and descended down to 25;000 feet and adjusted cabin pressure to 6.2 ^p. Monitored situation and continued on to planned destination. No further incident or action.my only concern was the structure of the checklist. The sixth item on the checklist states:descent..............initiate if required.there is no guidance in the checklist advising you why you would initiate a descent. The only guidance is in a memo dated back [a few months back]. It was my quick-thinking first officer who had this memo stored on his ipad that remembered it. I remembered the memo but did not remember the specific guideance for making a command decision. It would have been very valuable to have the information about getting the cabin pressure to a ^p of 6.2 written in the checklist itself.
