Toaster settings typically go beyond the optimal toasting time for a few reasons:
Versatility: Toasters are designed to accommodate various types of bread and personal preferences. Some people prefer very light toasting, while others like their toast well-done and crispy. By providing a range of settings, toaster manufacturers ensure that users can customize their toast to their liking.
Different Bread Types: Not all breads have the same thickness or moisture content. Thicker slices of bread or those with higher moisture content may require a longer toasting time to achieve the desired level of browning.
Temperature Fluctuations: Toaster settings are not always perfectly accurate due to factors like temperature variations, heating element inconsistencies, or toaster design. Having higher settings allows users to compensate for any fluctuations and still achieve the desired toasting level.
User Preferences: Taste is subjective, and what one person considers perfectly toasted, another might find underdone or overdone. By providing higher settings, toaster manufacturers cater to a wider range of preferences.
It's essential for users to experiment with different settings to find the ideal toasting time for their favorite bread type and desired level of doneness. Some trial and error might be needed to get the perfect toast, but having options in the settings makes it easier for users to find their preferred toastiness.
