I think the point needs to be made that, if stands only occur on the odd high profile race, then the probability will be that horses and horse men will not have acquired the necessary experience to fly the stand.
If standing starts were to occur with increased regularity on lower tiered racing, then that would improve the skill and experience of the horse and driver.
Anything to avoid the, 'all in a indian line' style of American racing. It is just plain boring.
