Interesting caloric deficit tool I found

Was Googling to see what people thought of the health-calc TDEE calculator, which I have seen both good and bad comments about, when I somehow came across this:

Just have java installed and put in some info, and it seems quite similar to the health-calc website. You input both your work/daily living activity AND your exercise activity, so I feel like it'd be a good way to recalculate your needs if you suddenly become way more active or you take a break from exercising for a week or two. I work out 4x a week ~5 hours a week overall, so I selected "Active" as I don't really think my strength training classifies as strenuous most of the time. I also am pretty sedentary outside of this so I chose the very light setting for daily living. Gives me an estimated TDEE of 2690 at 175lbs!

A cool thing about it though is that it graphs out your estimated losses over the time period you input. I started with my current weight and it gave me around 2100 to lose 20 lbs in 160 days. Inputting my starting stats, it has me at 2lbs lighter than I actually am for how many days I've been doing this, but I have not been in a consistent deficit this whole time, so that's pretty impressive! For current stats it puts me at ~168lbs at the end of september if I eat 2094 calories a day. Since I want to refeed weekly I'm going to start with 2026 6x a week, 2500 once a week, and see if my weight lines up well with the graphs (totals to 2093.7 cals daily on average). Of course I won't be eating EXACTLY 2026 calories every day, but I will be aiming to get as close to that every day to get the best results.
