Yes, you're not alone.
DS has always had higher A times then the avg's. We were on the 4 hour EASY with 2 hr A times at about 12-14 wks if I remember correctly. One thing that's REALLY helped me when it comes to tweaking our EASY is to read ahead on the "sample" easy's, since your DD seems to be ahead of the avg's as well it might help you when things pop up and tweaking is needed (ex, dropping the CN ect). As it stands my DS just finished the 2-1 transition, and does 5 hr + A times... (which is quite early considering he's 9-10months.) I agree with the PP, A times aren't set in stone, they're just guidelines
Good work being so in tune with your DD.
