my insulin to carb ratio is higher than 1:10, it's more like 6:10. Sometimes I do a bit less, other times a bit more. But I think I'd be running high sugar if I stuck to 1:10 ratio as well. Although your basal units you're on is much higher than what I'm on so it could be that your insulin to carb ratio isn't as much as mine. I'm on 13 units of lantus for basal at the moment.
