Toasters: a question

Who really designs toasters? I mean they’re fairly simple devices a heating element, a pop up bit, and a dial which controls how much it cooks your bread for.

And it’s the dial which has my puzzled for years now. Usually they go from 1-8.

• Level 1 will lightly toast bread.
• Level 1.5 will produce nicely browned
• Level 2 will burn it

So that’s levels 1-2 covered. So what the hell are the other 6 levels for?

If level 2 turns your bread into charcoal what kind of evil can be waiting out at level 8? I can only speculate my toaster was designed by someone who used to come up with weapons of mass destruction, and I deduce the remaining levels work something like this.

• Level 3 bread goes on fire.
• Level 4 burns down house
• Level 6 the temperature and pressure causes the carbon in the bread to fuse together forming hard diamonds.
• Level 8, the nuclei of the bread atoms are superheated, and fly apart annihilating matter, and causing a nuclear explosion.
