Oyr DS's set. this yr had over 150 C100s. There are small dets., but remember there are large ones too.
Also, depending on the cost of tuition, it is not necessarily the equivalent to a Type 1 or even a 2.. IE if you go to UVA and are in state, it is actually the equivalent of a type 7. The fact is approximately 2000 cadets graduate yrly from AFROTC and the big yr drop is between the 200 to 300, thus it would not shock me if there were 3500-4000 in the 100/200/250.
Now if there are 100 dets. nationally, than statistically you have less of a chance since around 900 HSSPs are awarded out of.a pool of 5k and only 100 out of a pool of even 3500. Again, remember your misconception starts with they are type 1s and not 7s, obviously Ivies will be 1's, but not everyone goes Ivy or private. The second misconception you have is that every det is as small as 50 for 100s. Many dets have increased in size over the past few yes because the AF has been combining the smaller ones into larger units to save costs. IE more xtowns, which means that even 5 yes ago there were more host units than there are today for those kids that were applying their senior yr in hs.
Even with all of that, this is a recruitment tool just like the scholarship. Your stats have to be incredibly strong to be offered this scholarship. I would say that chances are the college has to be your safety, and I mean not just barely a safety, but the true blue safety. And on top of that if I recall correctly, the minute you accept it, your name is taken out of the AFROTC HSSP, thus you are risking getting a scholarship to take to any school for this 1 school. Very few want to close out that option let's say in Oct., when the board does not meet until DEC.
