You can calculate the minimum using the QC required and Max QC provided in the table above. So for instance, lab 3 requires a minimum of 34 keys to clear (assuming you are super skilled and lucky), divided by 3 keys per set, which put you at 12 sets minimum. As for maximum, that kind of depends on how often you can play. So assuming you can spend the whole 3 days (72 hrs) playing lab 3 as soon as it unlocks until lab 4 unlocks 3 days later, then you'll have roughly 20-21 sets of keys max for those 3 days (assuming you are a zombie and don't sleep). You might think you'll have 24 sets instead since 72/3 is 24, but since new sets of keys will not regenerate until all 3 keys are spent, you'll have to take into account the time you spent to play using the first 2 keys, which I average it to about 10 minutes conservatively, and that's where I get that 20-21 figure from. And you do the same calculation for lab 4 and so on.

My advice for you: try to play as often and as skillfully as you can, use the unlock all labs glitch to buy yourself some extra time (method can be found at the back of this thread), and use tokens for keys sparingly (only if it's necessary).
