Are you a Type 1 diabetic? Just doing and seeing are different things if not done together ergo I've recently injected 6.5u for 110g carbs of which 90g would be from the brown basmati rice, I was at 4.6 on injecting, currently 6;4 with a slope up, the injection could and should have been 10 minutes sooner but I was cooking a pie for my little un, my blood will peak at around 7.9 before sloping back to mid 5's, allowing me to take a couple u for 2 Weetabix for my supper.
I can't see anything wrong with doing that either, nor does my Libre although I'll probably require 12g carbs in the shape of a two finger Kit Kat in an hour.
Sorry to be a pedant, but the mathematical law is called the “propagation of errors”, basically lots of small errors add up to a big one. The 20% error in carb values on labels, the 20% error in injected insulin becoming active, to name but 2; both become insignificant for small amounts of carbs and significant for larger amounts of carbs.
 
	 
 
		 
 
		 
 
		 
 
		
 
 
		
 The honeymoon? They didn't have them in my day
 The honeymoon? They didn't have them in my day  and like you learned of them on here, I think mine lasted 5 years plus when I look back, I do remember telling the doctor I reckoned I still made insulin but he disagreed and said it was all the sport that caused hypos
