Yeah, I'm by no means going to get my CFII in ATP times, but I don't think a year and a half to two years is too long.
But I'll tell you what, my hat's off to you guys at ATP that can absorb all this information in such a short amount of time. I fly about five days a week on top of five days a week of ground school classes and sometimes -I- feel like I'm trying to drink from a fire hose.
