Sounds about right. The way I envisioned it, that some of the very best techs would take days (literally) to complete researching while the preliminary ones a mere hour. As said before, some resources or buildings could help make that time shorter by shaving some hours off.

I dunno how hard it is to code such a thing, but to me that would bring some form of realism to the game actually having to wait for technology to be researched.
