I've got a PSE Carrera and I use 3 pins.

This may or may not work for you particular sight but you should get the idea from this.

I put all three pins in the same groove.
Set the top pin for 18 or 20, what ever you shoot the most.
Now put the rest in the same "groove" so you can slide them all up right against each other.

This means you can easily recover from any sight pin mishap. Damage the main pin and the others act as a stop for replacement, vice a versa.

Shoot the pins until you are at the yardage they are centered on, mine happened to be 20, 30, 45. Any damage and I can replace or at the worst shoot in one pin and the others are simple to get in. I recheck this every year and write it in white out on the inside of the top limb. Facing me when the bow is drawn.

This also serves as a quick check range finder.

For my set up, with the bow at full draw and ready to shoot a 3D deer target is top pin to bottom pin at 20 yards. Same with the 3D turkeys.

At 40 yards it will be just one pin to the other.

With this checked and easy to look at with just a glance at the last minute you will always have a pretty darn good idea if you are with in your "instant death" range.

I never shoot game animals at 40 but it serves well for the other purpose and you've got it there for fun at the range and 3 d shoots and stuff like that.

Most of these targets are 18 inches. If you check you'll find most 3D game targets have some aspect that is very close to this. Beats heck out of a last minute wild a22 guess and if you keep shots under 30 you'll always be darn close.
