What are the algorithms/formulas in use? Each prestige reset seems to reduce how high I can set the price before it starts turning demand red. I.E., with the first factory at 100% prestige, I could set quality and speed to level 10 and charge 65 per unit sold with full demand (no red). But with the 120% prestige level, setting quality and speed to level 10 again, I could only charge 55 per unit; Trying to set it higher resulted in demand starting to turn red. So I could not set price to 65 as I did a 100% prestige.
What am I missing here?
