This reminds me of another article from a while back which advocated 6 items in decreasing priority.<p><pre><code> 1 -> big item
2 -> medium item
2 -> medium item
3 -> small item
3 -> small item
3 -> small item
</code></pre>
I can't remember anything specific enough to find it, though.<p>Either could be beneficial, and choosing only the next three at first may be a good way of forming a habit.
