There is no contradiction. The main reason why the artificially low average is problematic is this : tour masters with lesser reflexes -- who positively cannot handle the current fast meter, unforgiving big hitters that are needed to cope with legend tees -- may inappropriately be bumped up to this higher tier, due to this artificially low average (which only requires that you achieve the odd excellent score, while the many mediocre ones are ignored). My personal example is a case in point, and I am not alone.
In short, as long as there is no decent slow meter, forgiving master driver, suited to tour masters with lesser reflexes, the artificially low average system will be a dreadful problem. Create this driver (not the most powerful, say 270y, but slow meter and forgiving), and those tour masters with lesser reflexes won't complain if indeed they end up in the legend tier.
