Heat map for Redo Size in SQL Developer...

I've gotten a lot of mileage out of my old SQL Developer Archive Log Count Heat Map report that I created in SQL Developer. I was recently asked to estimate the amount of redo that might be sent to a DataGuard standby. Searching The Google for this and I found some methods for calculating Network Bandwidth but I wanted to start with raw redo generated from an instance using information from v$archived_log.
