Feeding amounts?

I am curious about your feeding plans. I currently have a few 1200g snakes, I am feeding them 100g rats every 5 days, which is less then 10% of their body weight. I should I increase the amount of food they eat up to 10% of their weight? I also want to have them ready to breed this season. Any help is appreciated thanks!

The 10-15% rule of thumb is for hatchlings and juvies.
We feed all of our adults once a week.
Males get a small rat 60-80 grams.
Females get a medium rat 120-130 grams, sometimes they may get a meal that is slightly larger but never over 150 grams.
Once they hit these prey sizes thats it.
