With Jackson Howard rotated out this has gone from nigh-unplayable to extremely reliable wincon. If you have the resources to pull off two or three R&D runs in a row it's prettymuch GG. If you pull one of these off and don't see the agendas to stack the deck with, it still serves as reliable information to go fishing in HQ instead. Even if you fail to see things you want to steal you still get the chance to guide your opponent's next few draws.
Now that Jackson Howard is gone I don't think Deep Data Mining or Maker's Eye stand up to this. While they provide similar effects they're both more expensive to run, with Deep Data Mining requiring a rig built around maximizing MU and Maker's Eye not pulling as much information. While they both allow you a glimpse into the future, Indexing alone lets you change it. Against players running ambushes DDM and ME may end up getting you killed, while Indexing wont.
Adding "Freedom Through Equality" or Mad Dash to the mix makes this even crazier.
