I don't want to seem unkind, but I find your statement odd.
It's pretty clear if you watch any of the main family styles performing their standard long form that they are all just variations of the same thing. There is a video, for example, that has side-by-side comparisons, posture by posture of a Yang stylist and a Chen stylist doing their forms. A few of the names are different, a few of the movements are stylistically different and have different intended applications in mind, but they are unmistakably variations of the same thing.
Apart from the sequence, doing the entire long form at a slow, continuous, pace without jumps and fast movements has also been attributed to YCF. And, even if the sequence was always the same, not everyone did it the same way.
Many skilled practitioners perform the same sequence (form) in varying ways depending upon the day, what they want to emphasize and their age. Sometimes a given practitioner will perform his or her form slowly, softly and at uniform pace, other times, faster, harder and with varying pace. While YCF popularized a form that was performed slowly, at a continuous pace and without hard or fast movements, it seems unlikely that he "invented" the practice.
