But perfect technique doesn't matter if you are too tall to fit the pass in the floor space. A physicist could calculate how much space a 4'8" gymnast vs. a 5'4" gymnast would need with perfect technique to generate a given skill from x number of steps and a ROBH. Taking 4 steps into a hurdle generates way more power than a jump hurdle.I think that MC makes a valid rationale that staying within bounds is a direct result of good technique in acrobatics. Having good technique - speed, angle of take-off, etc will lead to more stable landings. Simone has both demonstrated the ability to both stay within the confines of the 12m x 12m and not stay in. An athlete who takes a step and stays in bounds should have less deduction than the athlete who takes a step of the same size and goes out of the lines - size of the athlete should not matter. Most athletes usually take line deductions as a result of a step/steps and not landing outside the floor. In another post (maybe this one?) Izbasa showed a great three salto pass that shows that good technique is important. If safety is the issue, why not do as is done in trampoline - have spotters on the corners of the podium and have safety mats on the floor off of the podium. Also, as pointed out above, changing the dimensions of the floor will be a huge financial cost for programs and federations who struggle already.
Are some gymnasts going to be limited by height - sure. But you could do the math to figure out how much space an average height gymnasts need to do certain skills with perfect technique and go from there.
