I don't think speeding up construction is worth it. Building and upgrading this disco to lvl5 costs $51M, so speeding it up apparently costs $408M. It saves a total of 232 hours, or almost 10 days.

But the break even point (3 totems & oracles) for normal upgrading is $51M / 25*$735 per hour = 2,775.5 hours (= almost 116 days). The break even point (3 totems & oracles) for speedy upgrading is $408M / 25*$735 per hour = 22,204 hours (= 925 days).

Of course this is 8 times as long, but speeding up upgrading tot lvl5 is so expensive that it takes 2,5 years to break even. I would wait those 10 days it takes to upgrade the building to lvl5 ;)
