There have ever been safe risk-managing hang glider pilots fully shunning badge and tiered rating systems wielded by insurance-influenced corporations; some of them know that no exterior rating will make them safe for a particular launch; they may be open to the full knowledge base including soaking in local wisdom about a site; they know that each launch needs their review of pertinent factors--none of which is a rating. Those who will take and live out being ever a student and ever an instructor may opt for the rating "HGP" or "Hang Glider Pilot" to be the sole badge to cover any situation among the thousands of possible situations regarding hang gliding. Such HGP might not fit other pilots; look to the other rating systems and adopt the flow that will bring out one's best for one's purposes. If none of the systems works for a pilot, he or she might create a framework of ratings that will fit.
I am seeing a variegated hang gliding flow in the US where it will be very appropriate for there to be several types of rating systems open to pilots. One pilot might even choose to go for ALL the options; or a pilot might aim for just one system of ratings; or a pilot might create his or her own rating system; a particular KIND of hang gliding activity might form a rating system to fit just that KIND of activity.
There will be in the US four or more rating systems for HGs and sites:





or even create their own rating system to respect their perspective of what hang gliding is about for them. Hundreds of perspectives over hang gliding are optional. Rating within particular perspectives is an open adventure.
Sites will have tiered rating depending on wind direction, force, and weather … calm, thermic, etc.
Sites will invite more respect from all rating systems depending on conditions. Recall how river rapids are rated; each person is to make a judgment about readiness to face a certain rapid.
