It is popular to dismiss alternate estimate models as potentially inaccurate,

the potential for _much greater_ inaccuracy in item-oriented methods.

While an estimate based on item extension is 100% **precise**,
in that it computes to single final number,
the method has no such inherent guarantee of **accuracy**.
