@Caterina As all my move-ins except one have been largely unskilled, I am obviously not doing a speed run, either.
When I did the much shorter Wonder Child Challenge, I started posting my story using the Week/Day format since it was only about six weeks long.
I've kept that posting format for my AC because I can look back and think, "Wow, I've been paying mob fees for X weeks," or "Gee, I haven't cleared any locks for two weeks now."
Also, the dating helps me keep track of all the birthdays, when they can start careers as YAs, when to move them out before they turn elderly, pregnancy schedules, breastfeeding & works schedules, etc. Yes, I'm very OCD, lol.
Having said all that, I would like to finish this challenge soon and start something else where my sims could run a restaurant, lol.
Ahhhh, I can't wait until Bodybuilder is cleared so I can redo the house.
