The pioneer helping others program was a total failure. From what I witnessed the pioneers thought they'd been dumped on and it was the person who studied with them originally who should help them or even more so, the elders who should be helping those "weak" and "new ones"--unless, that is, if the new one or weak one was one of the pretty people who everyone wanted to hang out with and let in on the pioneer clique.
As an elder when this program was going on, our BOE discussions never really dealt with how to implement this in a sustainable way, our BOE just thought of who was a pain in the butt and who didn't respond to being coaxed into reporting more hours and who we'd rather not have to spend a weekend morning with in service, and then send the pioneers to help them get their act together.
