Realistic weight loss expectations

I lost 1/3 of my excess weight by three months out, I lost 1/2 my excess weight By six months out, 80% At 1 year and hit goal about 18 months out.

I had a lot more to lose than you.

I think the planner is way off for me, I'm almost 4 months out and if I adjust the % to match what I've lost so far af the 4 month mark it's at 100%. And that puts me at pace to weigh 160 at 12-13 months out. I have some muscle mass and think that is impossible. But then again according to my scale(grain of salt....) i've Lost 15 pounds of muscle since surgery and 3 pounds of bone.
