A writer wrote this:
An all-night party on New Year's Eve provided me with a good excuse for not carrying out either of these new resolutions on the first day of the year, but on the second, I applied myself assiduously to the task. The daily exercises lasted only eleven minutes and I proposed to do them early in the morning before anyone had got up. The self-discipline required to drag myself out of bed eleven minutes earlier than usual was considerable.
I would construct this way:
I proposed to do them early in the morning before anyone got up.
Today, I had finished exercises before anyone got up.
What should we make of the writer's use of tense? When is it more appropriate to use before anyone had got up?
