I was just looking for the formula if there is one.. or is it a table of values?No. An additional level just costs too much at that point. (and at level 300, level 301 is only 0.3% additional production).
As an example from one of my sims (festival manager 3, shipyard 4, fireworks 2), Level 301 festival at 300/300/50 would cost ~13 minutes of production. And cut off a bit over 1 minute from the wait for 8.4Q itself. So you lose a bit less than 12 minutes adding it.
About the only justification for going a bit further might be if you were doing some of those wacky last tasks that cost *way* more than the 8.4Q to move on.
