If you consider a large pool of tech-teams from which a maximum number of five are simultaneously selected to perform all the country's research, then it makes sense to give the most active ones experience.
But that's silly, because the HOI2 research system is a mere abstraction of reality. The concept of using a small number of teams regularly while others remain idle most of the time is a peculiarity of this abstraction, it has no basis in reality. As an artificial concept it should not be given any additional effect on gameplay in a realistic simulation like HOI2
Silly ? Maybe so. But AFAIK real-life industrial conglomerates, engineering firms and study groups DO gain experience over time, as their engineers and workers get better at their jobs. Heck, they even train them, and try to keep them from walking to a competitor. Why would they do that if technical know-how was a corporate given that do not change over time ?
As an example, present-day European aircraft makers are very eager to develop UAVs partly because they know the European markets won't need any new military planes for the last 10-15 years, and working on UAV designs ensures their designing teams will keep their edge by working on new frames. So in 2015, these teams will be able to develop new planes - or to train new engineers to do so.
You can't "mothball" technical know-how and find it state of the art a few years after - it's true today, and that was still true in the 1930s-1940s. A company that works on a line of machine tools is supposed to gain an edge on this technology. A company that produces fighters will usually get better at it, and you'd be better off, as the lader of the country, to use their know-how to build your next-generation fighters than you'd be if you gave the contract to a company that was making cars or building destroyers.
Just my 2 cents off, but I'm pretty confident I'm hitting the nail on the head here.
