I'd say that you should tighten up in the early stages, defending your BB with 27% and 25% of your hands could be a bit too much. In the early stages I'm playing a very weak style which avoids me from playing big pots oop unless I have a premium hand. The stats for defending SB in the early stages could also be a bit too high. I guess the point why you're doing this is because you want to defend your blinds while the blinds are low because your 10/20 and 15/30 defense stats differ from the mid stages where you defend quite tighter. In the early stages the blinds are so small in relation to your stack so there is no need for defending with such a wide range...
I guess the other stats look good.
what limit do you play?
@coaches etc: please correct me if I'm wrong I'm just into SnGs the last weeks and studied some articles and stuff and I want to know if I got the point and if it's useful what I've said.
