This value is much bigger than, for instance, the default value for
the 450D at http://www.dofmaster.com/dofjs.html . In other words, if
people are using the calculator to work out what is acceptable, they
are setting higher standards than Canon - always a recipe for
disappointment!

The CoC is a value derived from the resolution from a "normal" eye at the "normal" looking distance from a "normal" sized piece of paper

By lowering the CoC value you set your "standard" higher.
