When Randy finally comes clean with his advice, I'm betting he won't be talking so much about running a blind or doing some obedience drills, or any other sequence of events prior to going to the line at the trial. He'll be talking about NOT TEACHING the dog that there is a specified ROUTINE you follow that leads up to a huge, beautiful flyer.

After all, if you followed the regimen in his OP every time out, would the dog not BECOME CONDITIONED to leaving the holding blind, running 2 blinds, and THEN ... cue the noise ... sitting down (maybe) to watch the marks. Taking off the energy edge, shifting the mindset to one of control and teamwork, etc. are a part of the equation and will help, but won't the dog quickly learn your new routine? AND on trial day, it all goes out the window. These dogs ain't stupid. They know where they are.
There are a lot of things you can do in training to establish the "what are we going to do now" mindset when you leave the holding blind. Cold honors are great, for example. How about getting out of the truck, standing in the holding blind while the birds are shot for the running dog, then going back to the truck. As many times as it takes. Keep the dog guessing and only once in a while, do the standard ready, set, go sequence. Get creative.
And for those of you that don't get many opportunities to train in a group with a trial atmosphere, all the better. Take advantage of those precious group training days with the club to work on your weakness. So what if you drive 2 hours to the training day and your dog only gets one retrieve. GREAT! Are you there to show your buddies how your high rolling, high drive superdog can do that triple? Or are you there to train?
On the flip side, I had a nice dog from show breeding who's desire was adequate but I wanted to amp him up a little and get him a little more excited and focused on "out in the field". So how would you TEACH this dog to get excited? How about coming out of the blind, taking about 3 steps toward the line and BANG, out comes a nice rooster about 50 yds. out! Let him go as it hits the ground! How many of those would it take to get him whining when he hears "dog to the line"? Same kind of deal. Expectations and anticipation.
Remember that Pavlov guy? Think about it.
