TL;DR
Normal science and infinite science should have different multipliers.What ?
I love using technology multiplier of 4-8 to slow down the beginning of the game where you can't keep up implementing those new technologies in your base.However late game I want to get those high counts of various infinite researches without any additional handicap.
Independent multipliers would be great but changing multiplier mid game in options would work too.
I can add to make it easier to fix that it was working well at the beginning but somewhere in the middle of updates the science multiplier broke and affected infinite research like crazy (mostly mining productivity).
