My only intent was to say that in my experience some data has been quite readily available. In our case it was enough data to understand our son's weight was trending in an unhealthy direction. We made small changes to the quantity and quality of food available to him and reversed the trend. The 75th percentile just happened to be the trigger in our personal case. I make no suggestion that it is an appropriate trigger in general, or that it equates to 'being too heavy.'
