Below is updated spreadsheet with ASGR and PrepGirlsHoops rankings added with average rank and sorted from low to high for this new ranking. Per my early post, I used Blue Star and the 30 players, they are the only service ranking Ava Learn at 29. Could probably remove that player but it's there so I left it.
Another disclaimer: Ideally I should have taken each ranking services top 30 and go from that..but as stated used the Blue Star top 30 as master list...I took the easy way out.

I greatly appreciate and respect your hard work. However, I offer the following
opinion:
Rankings 1-18 are valid rankings. These prospects are in the Top 30 of all five rankings. Therefore, this is a
true cumulative ranking. (Though the average ranking
score of Saniya Rivers should be adjusted to 3.3 because she is ranked #2 by Prospect Nation.)
Rankings 18-30 are invalid as a cumulative ranking. Why? There are two reasons. First, these rankings are biased in favor of Blue Star. Second, 4 of these players are unranked by one or more of the services.
Blue Star Top 30 Bias: You start with
only the Top 30 of Blue Star. This eliminates a number of Good Prospects who are ranked below 30 by that service.
Example: Laila Phelia (Michigan). She is ranked 31 by Blue Star, 54 by Prospect nation, 28 by HoopGurlz, 61 by ASGR, and 33 by PGH for a total of 207. Thus, her average score would be 41.4. That places her cumulative ranking above the player that Blue Star ranks as #20, Jada Walker. The same problem applies to Bree Hall (SCar) and perhaps a few others.
Players unranked by other some or all other services: The BlueStar bias is clearly apparent in Example one below.
Example One: Ava Learn (Purdue) is ranked #25 by Blue Star. However, NONE of the other services appear to have her ranked! Thus, she cannot have a "cumulative" score. The other services rank either 75 or 100 prospects. To be fair, let's assume that the other services rank her 76. That would give her a cumulative score of 329 and a cumulative ranking of 65.8. A similar problem exists with Macie James.
Example Two: Jada Walker. She is unranked by Prospect Nation who ranks 75 prospects. She has a total score of 167 from the 4 other services. To be truly cululative in relation to the other players, you should assign her a theoretical Prospect Nation ranking of 76. Thus, her cumulative score should be 243. That makes her cumulative ranking 48.6. Yeah, this one is more picky than example one.
Again, I salute your effort and it has been a great contribution to this board (the best their is). However, I only consider the first 18 to be
truly cumulative rankings. To be perfectly cumulative beyond that point, it would need to compare the top 75 of all 5 services.
Thank you for your hard work!
