As I pointed out before, the problem is the tee time format can be less fair in the first place. If anything, touring players should lobby against them, especially in areas where wind is likely to be a key variable for the type of course played. At least ball golf tries to average out the wind by keeping playinggroups together for two rounds and flipping the playing order betwen R1 and R2.
Ratings can also be less fair as a result. You don't break up the scores in a division and make adjustments based on wind conditions changing over the day (and you actually get paid out based on those), so why would you expect ratings to be done better than the actual scores? Roger doesn't mind taking a look at the SSA breakouts if the data is made available. But the PDGA hasn't mandated that TDs do that level of effort by sending in the tournament report with hour by hour groupings.
As far as the ratings range, 24-hole courses will produce a narrower range than 18 holes and higher SSA courses also narrow the range. The wind boosted the SSA in the final round and narrowed the range further.
