1 bowl = 1/4 stoned, slight hit
2 bowl = 1/2 stoned, halfway stoned eyes feel a lil different
3 bowl = 3/4 stoned, same as above but feel it a bit more
4 bowl = 4/4 stoned, same as above but feel it a bit more + feeling tired
5 bowl = blazed, same as above but can feel it more + feeling lazy + tired
6 bowl = blazed, same level I have each night before bed to sleep.

It is hard to say though because there are alot of different sized bowl pieces and I dont even have bowls I have spots and I guess 1 bowl pack would equal 2 spots.
