Yea, I think the main profitability table needs an overhaul, but that's a separate topic.

Actually, when a new limited-time building is first available, we have almost all the information needed to determine how profitable it will be. The income at lvl5 can be extrapolated from the lvl0 income (shown in the building info screen just before you build) and of course the size of the building is also known. The only thing missing is the repair cost, but again we can extrapolate the lvl5 repair cost from the lvl0 repair cost. So, the only thing we need to find is the lvl0 repair cost. Depending on the construction time and accumulation time of the building, it should be possible in most cases to construct the building and get it to break down (so we can find the lvl0 repair cost) while it is still within the limited-time window. I'm planning to do this for the next limited-time building that comes out.
