I always stick paper tape on the front side (for accurate markings) and on the back of the part (preventing chipping).So minimum of the blade penetrating through the workpiece.
It's been a long time since I did any of thus.
My mate also recommended having a plank of soft wood under the cut that gets scored as you make the cut.
I've got loads of hideous bright brown varnished banister planks for this.
