Taken directly from the page I linked from above:

"Note that if W + R > ReplicationFactor, where W is the number of nodes to block for on write, and R the number to block for on reads, you will have strongly consistent behavior; that is, readers will always see the most recent write."

Could you explain why this is incorrect? It seems the Cassandra devs use the definition of "consistency" from Brewer's paper, and Cassandra offers this level of consistency.

Your point about read-repair is correct when using QUORUM consistency level, but even then you can avoid that by using the ALL consistency level.
