When learning to strop, its best to take things slow and train your muscle memory the proper motions. Once those motions are engrained, speed will come naturally.
You really want to be careful about the flip. The stropping stroke itself should be swift, but slow down and flip very consciously, then do another swift stroke. As you are ending each stroke, the edge of the razor should be starting to lift off the strop, and you should lay the edge down slightly after you have begun the next stroke.
I would also agree that you should repair this strop. No use in buying another one until you know you aren't going to cut it to shreds.
