Does anyone know of and/or use this method of Insulin/Carb ratio?

Not personally, I don't use regular insulin which is what the 450 rule is. My understanding is that you divide 450 by your daily intake of regular insulin (500 if you use a mealtime one) and that gives you an estimate of how many carbs 1 unit of insulin will work for. I may be missing something but if you know how many units of insulin you take in a day and it is keeping your numbers in the right place you should already know how many g 1 unit covers.

The 500 Rule (aka 450 Rule) from Using Insulin and the Pocket Pancreas is a great way to estimate how many grams of carbohydrate will be covered by one unit of Humalog or Novolog insulin. This is your insulin to carb ratio or your carb factor. Once you know this, you can count the grams of carb in the food you want to eat and divide by your carb factor to find how many units of bolus insulin are needed to cover the carbs. This allows flexibility in your food choices because any number of carbs can be covered with a matching dose of insulin. I just pulled this up! Hope that helps! Sheila
