For a typical voter they don't want to look at a long list of pairwise <br>
counts to verify that a candidate has won every one of those pairwise <br>
contests.<br>
<br>
After eliminating the less popular candidates, and reaching the 3 or 4 <br>
most popular candidates, a voter can more easily focus on the few <br>
remaining pairwise counts.<br>
<br>
Consider the infamous Burlington and Alaska cases. A voter doesn't want <br>
to see the full pairwise matrix to verify the official winner won every <br>
one of those pairwise contests.<br>
<br>
Voters prefer to have fewer numbers to concentrate on when they are <br>
looking for the winner.<br>
<br>
The earlier rounds of elimination reduce that burden for them.<br>
<br>
That's a key advantage of the RCIPE method. It's also part of why IRV <br>
is easier to "sell" to voters than any Condorcet method.<br>

It's easier to understand. For voters. As explained above.<br>
<br>
That's more important than analyzing fabricated scenarios.<br>
