Niksasphalt8: I unlocked lab 4 when there was still 1 day and 14 hours left to wait, and this morning I just completed test 49 with only 1 day and 3 hours left before the end of the R&D. So I think that opening lab 4 was much better than buying 4 sets of keys in a rush to pass the final AI test (which I'll probably fail, but that's another story :-)).
