In the "Mechanics of Chassis development" https://igpmanager.com/forum-thread/45546 it states,
"Assuming you employ both CD & TD the same level as the team your research power will be 100 - (Team Level x 3) so:
L20 team research power = 100 - (20 x 3) = 40%
L15 team research power = 100 - (15 x 3) = 55%
L10 team research power = 100 - (10 x 3) = 70% etc."
Ok, so wouldn't I just get a level 10 CD and TD to increase my research? Or am I missing something massive?
