I think those numbers are a mistake. I hate those relative numbers, since the rest of the world publishes the exact RG on the X & Y axis or at least Min & Max. I think all V2 balls are extremely low RG: 2.45, 2.47, 2.48 in that region, which is 1.2 or 1.5 on their relative scale.
Check the Ebo website for actual numbers.
