Practically it is more than eight, because when multiple branches of managerial deposits cross on the project you are working on, all of sudden your work depends on decisions of dozens of people and their management chains.

Cutting this to four may give compound effect, but IMO this is focusing on the symptoms instead of the real causes like for example people being territorial or obsessed about their promo package. Convoluted managerial chain is often just a weapon to achieve your hidden agenda.
