We defined this pattern as any transaction having more than five inputs and more than five outputs, and looked at how many transactions matched this pattern (which is admittedly only roughly correlated with coinjoins, but as coinjoins are indistinguishable from other transactions we cannot do better than an approximation).
TBH, that sounds like a terrible heuristic to detect coinjoin txs Agreed - very few Darkwallet Coinjoin's will be detected by that huristic. I just checked my wallet and only about %10 of the Coinjoins had more than four outputs. The usual transaction pattern in Darkwallet is for there to be four outputs - sender destination, sender change, mixer duplicated amount, mixer change - and two to four inputs.
