[2.0.14] Bad percentages indicated in technology tooltips

[spacers]

The technologies which upgrade damage or increase productivity of existing recipes show percentage increases, but not in an intuitive manner.

Consider where no research has been done. If I hover over the cupgrade, it will say '+30% [+0% -> +30%]'. But it does not take into account that the preceding technology would already raise the speed to +20%. It would be better if 'Lab research speed 2' showed '[+30% [+20% -> +50%]', because that is what it actually does.

Furthermore, if I examine preceding technologies to what have already been researched, the same thing happens. If I have researched tier 5 research speed, I have a +190% bonus. But if I hover over 'Lab research speed 2', it says '+30% [+190% -> +210%]'.

At least, this thread has a more generic title...

It would be better if 'Lab research speed 2' showed '[+30% [+20% -> +50%]', because that is what it actually does.

Arguably, this should be +25% [+20% -> +50%],
or, because you shouldn't use percentages for changes above low % digits, ×1.25 [×1.2 -> ×1.5].
(Or maybe +25% [×1.2 -> ×1.5] if that one is too confusing ??)
