It literally just recalculates the value… so if you start with 1.4 x 1.5 x 1.8 x 2.0 then during Icarus you make a couple more combos into the rock bank it raises the 2.0 to something like 2.5, it doesn’t take effect in the calculation until you hit Icarus again. Then it updates and recalculates based on the new numbers.
