>>721674920lbs a month? Holy fuck time to link what I just said in the other thread.
Have you ever looked at studies? You can gain about 2lbs of muscle a month as an untrained beginner eating right and working hard. Genetics do influence this but the top .0001% tier don't make 50-40% more muscle a month like you may think you are. The weight you have gained is not all muscle. Bone density, fat, and other fluids like glycogen and water really influence this.
Try cutting. You will lose 10-5 lbs. your first week by just cutting most of your salts. Cut creatine out and you will drop up to a further 0-5 more(depending on your previous drop). This is your water and glycogen stores now not being maxed out.

Sorry about the shittyly formatted post and Good job.
You have made good progress but I would rather you be slightly disappointed than misinformed. Goodluck, zach
Also OP, this range is also limited by the fact that you are cutting, not gaining weight. Expect less than 2lbs per month cutting as a beginner. Enjoy the strength increase, though. Also, most enjoyably, enjoy going from 1pullup to weighted 10+
