Since you call them lessons I'm guessing that means you were after the "Preach My Gospel" change. I forget when in the 2000's that happened.
My mission president loved detailed weekly reports. He wanted to know how many 1st discussions you'd taught, how many total discussions (of the 6 standard discussions), how many total hours effectively proselyting (only up to 1 hr in for a single visit could count toward this total, hours spent reactivating (again, only up to 1 hr per visit could count), etc and the combined total was the "balanced effort".
Anyway, it's hard for me to imagine anybody averaging 7 actual discussions a day. Of the few times it happened for me, those were very exhausting days. Not sure what you guys would have counted as a "lesson."
Amazing to think of the way missions change through the years. The structure of the 6 Discussions worked very well for me, at least once it finally sunk in that I was only there to facilitate the Spirit's work and not to prepare them for some kind of test. The freedom of Preach My Gospel seems to get that message home sooner than the structure of the 6 Discussions did.
Anyway, I loved my mission, and I wouldn't change it.
