For me, story sticks are a massive pain in the rear. Unless it is something super compicated, like recently I had to build a cabinet that fit into three holes in a wall. Its just for when I'm concerned about jumbling too many numbers.
Learning to do this stuff in your head on the fly is a really important skill to have. It makes you faster, and more familiar with all of the numbers that are needed.
Say you have a 84" base cabinet, with three evenly sized openings at 26" and all of the stiles are 1-1/2". Finished end on the left, unfinished on the right.
If you're using 3/4" material and 3/8" dado's the math is pretty simple.
To cut your deck and if you have a 1/2" pocket against the wall you subtract 1-1/4" from the total width. 7/8" on the unfinished end for a 1/2" pocket, and 3/8" for the finished end. So a 82-3/4" deck.
For your two dados in the middle of the deck, (assuming you want the partitions centered).
From the finished end, add your stile (1-1/2), plus the opening (26"), plus the pocket (3/8"). And subtract the finished end. The dado will be 27-1/2" from the edge of the deck.
For the opposite side do basically the same thing. Add the stile to the opening, (27-1/2"), plus the pocket at the partition,(3/8), and subtract 7/8" for the 1/2" pocket and the unfinished end. The dado should be 27" from that edge of the deck.
To double check yourself, you should have 26-3/4" between the two dado's.
It would take me forever to cut out a kitchen if I were to use cut lists, or story poles. I do everything off of the drawing.
