This is Chinese numbers only. It doesn't take into account the Swiss 27j or Italian reps. I usually add 20% (closer to 19.8%, but 20% makes the maths easier) to the official figures to get a more accurate real-world spread.
Your 93% is actually closer to 94.5%, or 95% if you take Ubi's data into account as well.
ps. Please note, we're working with the statistics of Super Reps only. If you take the unclassified reps into account, you can effectively multiply JohnG's numbers by a factor of 18.1, meaning you're over 98% probability it's a rep, seen from over 8' away - obviously, the non-Super Reps are identifiable as reps within the standard 8' mean distribution distance, according to the international designation definition of Super Rep.
