Doh! Sorry - wasn't being facetious, was being thick ;o/
Haven't put in enough time to bother interpreting, except it obviously implies one particular trader doing all the same-sized (or same split ones) each time, and sometimes the near-identical broker code confirms that. Not always obvious which buy/sell column they belong in, other than the direction the price then moves.
Similar behaviour several days a week lately. Daily total among the disguised lots is not huge, but if it's the same player each week I guess there's quite a lot gone through.
