Did you get your answers to this? If not, post back. I don't remember off the top of my head but I could figure it out again in a few minutes.
I have mine set like this:
Exercise 1 - -50% (This is if I am at the gym working out. I typically have a snack or something 30 minutes before and when I bolus I choose this and it reduces the calculation of needed insulin by 50%.
Exercise 2 - -10% (Same as above but more like an after dinner walk or light bike ride)
Illness - +25% (Still not enough for me personally but not pushing it. I generally do not worry about by BS too much when I am sick other than to keep it reasonable).
Stress - Same as above....
There is an Accu-Chek users group as well that is real good for answering questions and a representative from the company pops in every now and then and will offer assistance as well.
