If you are not using the precision trolling ap on your phone I suggest strongly to get it. Dive curves that come from the bait shop or directly on the back of the package are not really accurate.
Some guys also don't trip their boards. There are several problems with this. One being that everytime you put pressure on the board (not tripped) it wants to do what it is designed to do "cut out to the side of the boat". As you get closer to the next board you and up having to hop over the line. These guys usually start letting out line in order for the board to somehow fall to the back. Still doesn't matter however when they start putting pressure on it. This also takes a ton of time and you are prone to lose fish.
One thing I learned salmon fishing: The quicker you can get the fish in the boat, the better you are. Wish salmon, I NEVER let them run. I torque the drag as tight as possible. With walleye, I want to get them in the boat as quick as I can. No reason to screw around with them. I've watched people battle fish for 20 minutes. Meanwhile, I've caught 6!!
It takes practice but you will get the hang of it. The key is knowing how to make the setback and knowing the distance to stagger your boards. I used to run all of my inside boards so they wouldn't trip. This is easy to do however, you always get confused putting them back out and end up putting it in the wrong spot. For that reason, I simply switched all of them to trip mode!
