You probably have seen people use the term “sleepy scale” when rating the quality of their disc golf discs. The phrase was originally coined by a member on Disc Golf Review forums (with the name of sleepy) and people have run with it. Here is the explanation on how to rate your discs with the “sleepy scale”
10 – Never been thrown. No ink. Brand new condition.
9 – Field tested or used for one or two rounds.
8 – Lightly used with very minimal wear.
7 – Used with some minor dings or scuffs but still in good shape.
6 – Typical used disc with the usual dings, scratches but still worthy.
5 – Kinda beat, significant wear, has lost a good bit of its stability
4 – Beat up turnover disc with some evident war story wear
3 and below – Extremely beat up disc, probably not worth much 🙂
