Ratio for first insulin of the day

My ratios are normally:

Breakfast 3:1
Lunch 2:1
Dinner 2:1

If I have a lie in and don't eat breakfast until lunchtime should I be doing 3:1 or 2:1?

I think the ratios refer to resistance levels to insulin at those three or four main times in the day........

Mostly everyone is more so in the monrning as the body wants glucose to start off the day.....

Stick to the times of day
