I've been working with the USKP and I've found forms for weapons and amor that are based on templates yet have edits to records other than name, enchantment, script or value.

A good example would be "Grimsever", because the USKP actually changes the template, but also changes the model record and a load of other stuff. creationkit.com (http://www.creationkit.com/Weapons) says that these changes won't have any effect unless they are one of name, enchantment, script or value. Is creationkit.com wrong on this?
