The way you should look at your stat points are, "How many points do I need to hit a certain benchmark?" For example, if you are aiming to cap attack speed at 81% for ravager (say you are running sniper set with 10% attack speed secret stones and 25% attack speed eido) you will need 46% speed. You should then look at your expected buffs in normal combat situation and build your stat points from there. So say you expect yourself to have 40%, you would take the 6% speed you need and divide by .3% speed per point, then you will see you need 20 points. Obviously you can try different things and make tweaks as you decide to make different build choices elsewhere.
