ive told you this a thousand times lol
yes it does lv 1 intergalatic research station adds your 2 highest research labs up
lv 2 adds the 3 highest up etc
so for example if you have a level 12 and level 6 labs and you have the intergalatic research station level one when uprading your research lab will work at the speed of a lv 18 lab UNLESS the research being conducted is to advanced for the minor lab for example to get hyperspace technology you need:
[color=#00FF00]Energy Technology(level 5)
Shielding Technology (level 5)
Research lab level 6
so if you only had level 12 and level 6 the level 6 lab would be unable to speed up the research of the hyperspace technolgy because it is not at the required level
