So true. Fast splits are only as fast as you think they are. That means that if you're shooting "fast" splits, you're shooting on the edge. Shooting on the edge gives you the feeling that you're going fast. While, if you back off as little as .02 per split, you'll have the sensation of being much slower, and you will have a feeling of total control.
You won't lose time and your points will be better.
Let the timer be the judge of how fast you are. All you have to do is get the points.
