Some data on Wake preferences.  Due to drops and unforseen circumstances, we ended up with 17 extra rounds of commitment.  Since we were committed to losing 0 rounds due to pref, we went through 7 rounds losing no rounds at all.  That left 17 extra for round 8.  To resolve, we gave individuals with 8 round commitments the round off (unless they had opted in to the diversity designations).  For the remaining 10 rounds extra we ran the pairing and ensured that no obligated rounds from those who opted in had been lost.

Here's the results by round:

Round 1     16.09
Round 2     16.41
Round 3     15.43
Round 4     15.11
Round 5     15.11 (14.85 in - 18.09 out)
Round 6     14.94 (13.43 in - 20.89 out)
Round 7     15.68 (12.45 in - 22.20 out - 10.12 break)
Round 8     14.96 (13.03 in - 17.08 out - 10.32 break)

Totals        15.47 (14.85 in - 19.41 out - 10.21 break)

The other metric I tracked was the overall diversity of judging for the top 15 rounds in each of the powered rounds - 90 total debates).  I noted that 68 different judges had judged that subset of rounds at Kentucky and suggested that I was aiming for 70-75 different judges at Wake - though it wasn't a factor in the algorithm.  We ended up with 75 different judges judging the top 90 debates during the tournament.

One more comment on the graph.  It represents only prefs actually entered.  4 teams did not enter prefs so their data is not represented.
