Here's the thing: you need about 1.5 times (roughly) as much in volume to achieve the effect, but it's very different than smoking. If you've ever had creeper bud, it's like creeper to the max, you will sometimes get frustrated after 1hr+ of waiting then so oh well and go on about your day, only to be sitting there talking or driving and say "oh no" cause once it hits, you just keep wondering damn, will i ever stop getting higher?!?! Also, if you do this be prepared to not do much that day because it lasts a LONG time. And the burnout effect seems worse to many people. .6 should be enough provided you do everything right (organic peanut butter, don't burn it, grind it up as much as possible) Good luck and bon apetit!
