What you also need to remember is that it will take 2 or 3 days for the remaning background insulin to burn out your system.. So might find after a couple of days things get a bit rocky, but that's when you can start to pin down your basal rates with basal testing etc, easier to sort out the night times first..
As to your verious carb/insulin ratio's remember if your basal is out so will these be, so basal get the basal right first before tackling the fine tuning of the carb/insulin ratio's..
But saying that some nice results for the first day indeed.. Hopefully an indicator that your settling and working out is going to be relatively easy affair
