A scientific experiment....I like that idea!!
I don't quite understand the bolus calculator though- for example went to nandos before the cinema and had a truck load of carbs....bolused and all was well. Then told it I was having more carbs but it recommended no bolus as I had enough IOB- surely it should know that the insulin I have taken is to cover previous carbs? I gave the bolus anyway but it's not what the pump recommended!
