You need to consider other factors into the equation, i.e., class (barbarian, paladin, etc.), skill (frenzy, zeal, etc.), and other sources (fanaticism, burst of speed). Google "Diablo 2 attack speed calculator" to find tools that can calculate those variables for you.
Edit: As a ww barbarian, you need 39% Ias (including the 30% on Grief) to reach the last breakpoint (4 ticks). With 30%, you've got 6 ticks.
