Tis hard to explain
Just before you attend the course, they take you HbA1c, weight etc, as your bench mark of control, this and all your future results get sent to dafne HQ as part of the constant monitoring program... My consultant did prewarn me, even he doubted I would learn anything new..
Not sure whether I would say I learnt something new as such, but certainly came with a better understanding of what I was doing, also a wealth of information based on other peoples experience, all resources/knowledge that could be used or adapted if necessary at a later stage...
If the opportunity arise to attend dafne again, I certainly wouldn't turn it down that's for sure
