No, more than two hits is NOT a chain. Especially over the course of an entire war like you said. You are quite obviously from MTP, because only a delusional MTPer would think that three hits in 80+ hours in a chain. The definition of a chain is something more along the lines of "losing more than than half your land within a couple of hours" or "Five or more hits within a couple of hours"
If it's not done within a couple of hours it isn't a chain.
