My Results So Far With New Grappling Dummy

Hey guys.  So I've been coming home every night for 2 straight weeks and practicing with the dummy.  It's the Submission Master one with the bent legs.  I wasn't too sure how much I'd improve especially after only seeing mediocre results when I used to use Combat Sports dummy (although it was more for GnP.)  Here's what happened.

I decided to practice just 2 things: Guard passing and triangles.  I limited it to 3 types of guard passes and hitting triangles from different positions.  After a week I noticed, while rolling in class, that I was passing guard like crazy.  At first I thought they were just letting me pass but then after the roll they told me otherwise.  I was defending guard passes more effectively as well because I'd just reverse the scenario in my head and use my knowledge to keep the position.  My triangles improved too.  My teacher even commented that every time he looked over I was either attempting a triangle or I had someone in one, not that I finished them all.. probably 30% of them)

Now I'm in week 2.  I noticed that I'm not gassing out like before because I'm not constantly defending anymore on the bottom.  I now seem to have an offensive plan that keep my partner on the run.  My eyes feel like they're on automatic and I can just see triangle openings and it just happens from there.  My finishing percentage went up and I'm excited to continue growing and honing in on my weaknesses.  Anyone else practice on a grappling dummy?  Any suggestions on how you train with it?
