I think that such timing is quite good. Team game is very different from normal and even in simple team game players NEED to constantly discuss and make decisions together. If they want to be successful, of course. 6 hours per 10 turns is a bit little though, IMHO. 8 might be better.
Also, from what I read at the previous game topic, it was mainly cooperation, discussion and coordination what won that game. Smaller team will always be a subject to rush and without proper discussions when each nation is left on its own it has no chance at all. Each arrow on the map may be crucial and so is each soldier's life. It is not nearly an exaggeration.
I also think that vets should be given some advantages (for example, more capital pop or selecting nations first) have a chance to be successful.
