The MEMORIAL is a barometer....it establishes 5 fundamental things.
1) It measures Effort made in the preaching work to encourage attendance
2) Spring cleaning and upkeep of the hall and grounds
3) Ability to discern how many are affected by the mental disease of "believing" that they are anointed even after the ORG has stated they are not
4) Opportunity for elders to sit in a row and serve each other the emblems that way distinguishing them from the ordinary in the hall
5) Chance to "guilt" the congregation, particularly the inactive or irregular who invariably show up for the fiasco
