Planet spending works in weeks. That in it's self is annoying to me and would love to get rid of it and have it tell me actual amount of money it needs to complet the project. But that aside, what the game needs is a week 0 for completion of building uints. I'm rarely interested in if something will be done in 2 weeks, which is what week 1 can mean in real terms. In game terms we are playing in week 0. So if something will be completed at the end of that week, and thus ready to be used the following week, then that should be displayed as week 0 completion, never as week 1. Having week 1 for completion for both current and following week is a misrepensation.
