Another member of this list was once (possibly still is?) responsible for an application with a database whose DB_BLOCK_SIZE was set to 4608. Mind you, it was most certainly not their choice, but instead was mandated by the vendor.

The reasoning for the setting? A "very important" table in this application was deemed to have an average row width of about 4100-4500 bytes or so. The rest you can guess...
