Yeah, I've always felt the adult stages were a bit off, especially once they added the toddler lifestage, and now with university it feels even more unbalanced. It doesn't make sense to me to have 37 sim days represent ages 0 to 18-20 (baby through teenager, about 18 or 20 years) and then have 48 days for what I usually imagine as about ages 20 through 60 (40 years, so twice the length the pre-adult stages). That's 37 days for about 20 years but then 48 days for the next 40 years after that. By all rights, imo, young adult/adult should total twice the amount of time as baby through teen in order to be proportional, so young adult/adult together should be at least 74 days. Fortunately there's MCCC, and use that to make the young adult and adult stages proportional to my preferred specifications lol.
