The formula documented in the pub assumes that each lock table entry is 8 bytes wide. In many cases, that's bigger than it needs to be. The number of connectors determines the actual required lock table entry width.
Note that CFSizer and the Sizer utility (the documentation for which you are quoting) are not the same thing. CFSizer is a web-based tool (http://www.ibm.com/systems/support/z/cfsizer/ - the URL Lizette provided is obsolete but will be redirected to the right site) which is used to calculate structure size when you're starting from scratch. You provide a characterization of the application workload, and CFSizer uses that and an application-specific model of the structure usage to estimate the number of structure objects (list or cache entries, data elements, etc.) the structure must support. Given that and knowledge of the structure's fixed attributes, it calculates the required structure size via a call to a CF located at IBM Poughkeepsie. The Sizer utility is a batch job or started task which you can download from the CFSizer website's alternate sizing techniques page (http://www.ibm.com/systems/support/z/cfsizer/altsize.html). It is useful when you believe that your structures are already sized correctly for your current workload and CFLEVEL, you are migrating to a new CFLEVEL, and you want to know how big your structures have to be to preserve the same capacity in the new CF.
