In GA when I first started running there were 5 classifications. Top 2 at region went to state. I remember 3 guys going 9:20 at region and one being left out. (Erassa)
Fast forward to my senior year and there is 5 classifications and top 4 go to sectionals then top 8 at sectionals go to state. I thought that change would be easy for me to qualify and it turned out to be way harder than the previous 2 qualifier system. The state meet truly had the top 16 runners and the talent level was evenly spread throughout the classes. 5a was almost always the most competitive race and 2a was the slowest race.
Fast forward to present time in GA I believe they have a 1a Private, 1a Public, 2a,3a,4a,5a,6a,7a. It definitely dillutes the state meet competition level in my opinion. I was ranked 8th and 10th my jr/sr years in hs. If I go look at milesplit now with the new classifications I would have been state runner up my junior year and 4th my senior year. There are definitely worse states than VA in my opinion.
