Question about "blue chip ratio" rankings.Does it take into account players who leave

transfer or have career ending injuries? I don't think it does.Looks like he just adds up 4 and 5 stars signed
over a 4 year span and adds them up.

This is from the site

All signees count. Transfers and walk-ons do not. Transfers are not governed by recruit rules, are not rated and, though they’re important to every team, are rarely consequential enough to turn a non-contender into a contender. Walk-ons are almost never rated. Sticking with signees helps to standardize the process.

I use the 247Sports Composite, which blends the three major recruiting rankings by 247Sports, Rivals, and ESPN. It formerly used Scout as well, but 247Sports bought Scout, and its rankings no longer exist.

I manually curate it each year because publishers of some of the team sites erroneously list walk-ons under enrollees or signees. Removing non-scholarship players is by far the most time consuming element. Also, older classes are wrought with errors. For data in this current decade, it has improved, but more than a handful of team site publishers still lump in zero-star walk-ons with the others.

I also do not remove signees who fail to qualify academically or who are denied admission due to off-field reasons, because it’s difficult to track, with so signees on so many teams.

He also doesn't count transfers coming into programs and still counts signees who don't even qualify.

It's a pretty lazy way of doing things and somewhat deceptive.
