Intended size of Research Teams effects?

[Arakash]

to give some numbers to it:

If your best designed engine is 10% higher than your design skill, you increase 0.4
if you best designed engine is lower by 10% than your design skill, you decrease 0.4

if your best engine is above 10% skill, you get up to 0.5 bonus from research.
if your best engine is 10% lower than design skill, you get up to 0.4 bonus from research.

So your best engine is 0, your skill is 5, you max out research your skill does not move... if you do half research you lose 0.2 skill points.

Thanks for sharing those numbers, they are extremely useful in understanding the system.
One last question mostly for clarification, when you say that "best designed engine is 10% higher than your design skill" are you referring to the overall rating of the engine?
