Please don't take this the wrong way, but if there's one thing you'll here on this site perhaps more than any other it's this: don't compare yourself to others. There's nothing good that can come of it.
Even if you found someone that was your exact same starting weight, height, and even had surgery the same day, there are still way too many other variables that could impact your progression. Just some examples: age, physical fitness, %body fat, basal metabolism, diet, bougie size, surgical complications, etc.
Honestly, it sounds like you're doing fine. If you're not happy with your loss so far, talk with your bariatric team. They may have suggestions for you such as increasing the amount and type of exercise and/or changes to your diet.
Best of luck!
