I hate to disapoint you, but one fasting won't mean a cracked morning basal settings, it will only give you an idea where best to make a change to your settings..
Don't make two many changes at one go, just change a hour or perhaps 2 at first, and see how this pans out sometimes a small change can make a lot of difference later...
It can be a frustrating slow process at times, but change too much and you won't know what did and didn't work.. I've seem people who thought that they could change this and that because they had thre fasting test, then got themselves in a right old pickle, as they hadn't taken on board that changing the basal in the morning, would relfect also in the afternoon, which they had also changed because that was out of kilter at the same time etc...
My fist full set and cartridge change, took me round about an hour to accomplish, as I checked then doubled checked the manual, and then rechecked it and doubled checked that at each stage :lol:

But now after 2 years of pumping, I've got it down to a fine art and only take 5-10 minutes... And a cannala change is down in a flash
