The new sticks are an improvement.
I just want to vouch for the fact that with the old system, CMs were trained to make measuring as consistent as possible, and the only way a height stick could change as a result of wear and tear is to become shorter . Also, the entire point of height requirements is the child's safety. When measuring, here are some helpful hints:
Do
1- have the child "stand like a soldier" (feet together, shoulders back, facing forward)
2- if you aren't sure of your child's height, don't get them hyped up about the attraction until after they measure up, and always have a plan-B.
Don't
1- have the child stand on their toes. This will only make the measurement process take longer, confuse the child, and make you look less credible.
2- give the child a "tall" hairdo. a ponytail on top or "extreme spikes" will make it more difficult to gauge the child's acutal height, which takes longer.
The measurement is intended to be from sole of foot to top of skull. Hair height has nothing to do with body size, which is factored into the design of safety restraints and ride vehicles. The system is not in place for its own sake, it is there to protect your child, and "fooling the system" is ultimately not in your child's best interest.
The new sticks are one step toward consistency, which is always our goal. Testing continues at Disneyquest, and if the system proves viable, it will certainly be implemented at the parks.
