The VAST majority of P&Y members are Associate members. The VAST majority of record book entries come from Associate members and non-members (that's right, you don't have to even be a member of P&Y to enter an animal.)

Regular and Senior membership takes an entirely different level of commitment.

Associate members are not eliglible for regular membership until after 14 years of Associate membership. Tack on another 8 years between Regular and Senior membership.

i.e. They only want Regular and Senior (voting)members that have demonstrated long term commitment to the club. Yes, part of that commitment is participation in the records program. There are several other requirements as well.
