I think I remember you were in our squad at the March OB match, Howard right? I remembered being your RO for many of the stages. Some of the stages you were only down a few points but the time is what's hurting you. And then when you tried to rush on a few stages, either FTEs and mikes were there. I would recommend you seek help from Aaron @ DVCperformance.com. He does private classes, I've heard a lot of great reviews and a really nice guy. I know he is a M in Open and I think also in Limited.
During winter months, we dry fire a lot which I believe helps a lot. But you need to know how and what to dry fire. Otherwise to undo all the wrong or bad habits is just as bad. Just hang in there and you will get better.
