Tadd, note that when someone used 3.0 rubber for first grind, then his rubber wasn't used (recovering... he got 1.5 now). He's grinding again up to 4.5. That means his last grind is 4.5-1.5=3.0 (3.0≠4.5)

I'm not sure how does multi-grind work but i'm sure it's not simple addition (maybe someone can describe it).
Don't believe everyone saying "That was 4.9 rubber grind! How could you get in?!".
