Sorry, hadn't checked this since your last post. There's nothing wrong with your formation, thats as good as it really gets. Neither their pikes or normal infantry should be pushing past your pikes that much. Try switching your pikemen out of defensive mode when fighting their pikes, that is suppose to help. My pike vs pike battles tend not to last long so I can't tell you if it helps. I guess just don't let them stay and only fight your pikes, flank them with your good supporting infantry as fast as you can. Not much else I can see/say.
