Good stuff M2M, just got done reading Phase II.
I think that 18% could be obtainable at the $5 level, while maybe something more like 12.5%-15% would be obtainable at $10.
I went on a heater right before I started my operation too, winning 9/10. But ever since the start of my OP, I've been struggling to break even.
Good luck with everything man. You're a winning player...remember that.
