Polish numbering systems - any rhyme or reason?

I've had a tough time understanding the numbering system polishing manufacturers use (IE...85RD, 300D, etc).

Anyone have a good breakdown as to why they name these products different numbers?

 

Lol, umm no idea. Might be random really.

 

They do even better things like have two products PO85RD and PO85 3.02 that for two totally different polishes in terms of cut -- it's German!

 

Lost in the translation

Menzerna GMBH EU Abrasive Levels and Reference Numbers

• FG S500 – Fast Gloss (POS500): Cut 10/10: Gloss 5/10
• PG 1000 – Power Gloss (POS34) Cut 8/10: Gloss 3/10
• IP 2000 – Intensive Polish (PO91) Cut 7/10: Gloss 6/10
• PF 2500 – Power Finish (PO203) Cut 6/10: Gloss 8/10
• FF 3000 – Final Finish (PO85U) Cut 5/10: Gloss 9/10
• SF 4000 – Super Finish (PO106FA) Cut 5/10: Gloss 10/10
• SW - Sealing Wax (PO60) Cut 2/10: Gloss 10/10

The above numbering system is being used in EU, it seems thet are using grit numbers in their system (i.e. PF 2000 will remove 2000 crit scratches)

I'm still trying to figure out Menzerna US nubering system
