I like your plan, you should undoubtedly achieve at least 5 pounds a month and that’s still at bare minimum 60 pounds per year. You’ll be well into your 230s by this time next year, and that’s already pretty heavy by itself! A gradual gain is definitely better to really enjoy every stage from slightly chubby to very chubby to fat and beyond. Plus people won’t suspect as much if it’s fairly slow like you’re doing. Good luck to you and your gaining journey! P.S. be careful with the melted ice cream before bed tho, that can really blow you up fast.(might increase gains to 10 or more per month)😅
