First off this is only speculation and by NO means am I an expert here. Today after talking with the person that got me into this play(a couple years ago) I was left with these thoughts.The initial drill results are a little bit like a game of darts, just keep poking around the outside edge score some points and work your way inward, eventually you will be shooting for the Bullseye! That is what I choose to believe is happening here and We are all hoping for a Bullseye. I look forward to future Drill and Trench results and still believe this will be a game changer. Hang in there SLI faithfull better days are yet to come. Cheers.
