Phil, I think you answered your own question. The idea that you feel rushed is the key. It takes a lot of time to get past that feeling but when you get every part of your foxtrot on time you will discover that there is much more time available to do each figure. Make sure you use all of the slow part of each figure, drag your toe or whatever to make it slow. This is where you probably are going off time. There are no shortcuts to getting your foxtrot to look like the champs, keep at it. When you get this timing straightened, you will feel you have all the time in the world to execute.
