Okay, at this stage, just to confirm, the connection is in the initial letter of the answer, repeated
So the person who said "Annual income twenty pounds, annual expenditure nineteen nineteen six, result happiness. Annual income twenty pounds, annual expenditure twenty pounds ought and six, result misery." would (for this quiz) be "Mr Micawber". "Wilkins Micawber" would fail to get the repetition!

Two more scores, Katlaughing with 17½ & The Walrus with 20
