This is truly the ne plus ultra of pointlessness.

It depends on the purpose you have in mind for the toast. For a peanut butter sandwich, the merest introduction to the toaster is sufficient. For marmite on toast, on the other hand, a good stay in the toaster is required, producing at least a dark brown, with some blackening acceptable.

Don't overlook also the need to recalibrate your toaster for different breakfast time comestibles, for instance I find crumpets require a surprisingly high setting, and hypothesise that they have higher thermal conductivity than bread, this conducting heat into the cold heart of the crumpet. Pitta breads, on the other hand, seem to need no time at all before the steam inside is capable of inflicting third degree burns. Pity tht poor toaster ingenu who puts a pitta in on a crumpet setting.

As for the toaster, It has to be a dualit 4 slot.
