I do think the rankings have been adjusted since week 1 and reflect a more accurate (no one will ever be happy with rankings, no matter how they're done) portrayal in the current week.
For example, the first week there were 10 AA Girls teams ranked and 5 A teams ranked. This week there were only 8 AA girls teams and 2 A teams in the rankings, which is more in line with a top 10 Girls A/AA like last year.
Also, in TL Hanna's case, this might be their best team ever, but if their top win is over a Dorman squad that is far weaker than in year's past, then adding wins over Westside, Woodmont and Easley won't build their resume enough to keep them in the top 15. Once they face Greenwood, Wren, and other strong non-region competition, the quality wins will earn them a place.
Are the rankings actually done by people "outside" the state now? If so, this would make the early rankings of teams with good records, but who recorded wins over weak opponents, make sense.
The first week's rankings SHOULD be skewed, because people outside the state don't know which teams are traditionally strong. This is a downside, but the positive is that teams will no longer receive preferential ranking based on how strong they used to be.
What we should see in the long run is more teams being ranked, more teams being ranked highly that previously would have been "low-balled" by the powers that be, and more traditionally strong teams NOT getting ranked because they have losing records.
Change can be bad, and change can be good, and in the end most people both love and hate change. The new scoreboard represents change. It is not perfect. Some will critique it and some will praise it, and it in turn will serve to make things just a bit more interesting...
