Slin on carb-up days?

[justalittlepup]

I've got a question on slin. I read an article on using slin on a keto diet. No don't jump the gun, I know you need carbs for slin. But it was talking about using slin on your carb up days (normal hits of 5-10 iu's) and after your last carb meal take 2 iu's every three hours till you hit the glu level you want, therefore get you back into ketosis in less then 12-16 hours. Anybody heard or done anything like this?
