I was thrown out of RnD by the RD once, dude said I was the worst person ever because I had no idea what I was doing, just causally taking things and seeing if they up'd the tech levels, and that got me really mad. I couldn't play the rest of the round after that...
I can set up both the sing and tesla in under 2 minutes, successfully, I can do surgery just as fast (unless it's recently added things that get confusing), but RnD is hard for me because nobody will teach me and there's nothing on the wiki about the order you're suppose to scan things (for some reason I have no clue about).
