I dont understand their metrics at all, and to be honest it doesn't seem to make any sense. Let's take a closer look:
Omega 7 Pro - Spin 5.4
Vega X - Spin 5.4
Vega Japan - Spin 6.0
Omega 5 Tour - Spin 7.7
J&H C55 - Spin 7.7
Vega Korea - Spin 6.4
J&H Z52.5 - Spin 6.0
The Omega 7 Pro, which was their high-end rubber lineup until a few weeks ago, is as spinny or less spinny than the cheap vega line? (Vega Korea and Vega Japan are even supposed to be spinnier)
Omega 5 Tour, a rubber from a few generations ago that no one is using anymore, is as spinny has their top-end rubber right now? (C55).
Vega Korea, a random 30€ rubber, is spinnier than a rubber that is supposed to be a "custom model for National Team Players"? (Z52.5).
Why are Spin and Arc even in the same category. Would be nice if they'd care to at least explain somewhere how to read those stats
