Drive to 11-13%

So I am a regular in the gym 4X a week, getting stronger slowly but steadily. Moved from DC to Dallas in November and joined a new gym. One of the perks was that I got a free body testing done and it was 1/2 going forward (so $20 a pop). Figured I would start the new year off right and get it done then do quarterly scans to see where I am.

Went in yesterday and did 2 scans; Dexa and a Styku. BF was about 14% on Styku and about 17 on Dexa (not sure which one is better but just to give a frame of reference). I tend to think the higher one is a bit more accurate as I have good definition in my arms but only slight definition in my abs.

As an aside, to get into the 15% range as many of you know takes a good amount of work and I felt a great sense of achievement. All those nights of roasted veggies and chicken thighs paid off (was in the 23% range a year or so ago)

Now to my question; how intense is the next 5% going to be? I do not count my macros as of now, but eat 6-8 oz of protein lunch and dinner every day along with 2-3 servings of veggies (at least 1-2 of those servings being green). I eat potatoes probably 3X a week, with 2 of those being sweet potato on deadlift/squat day. I couldn't tell you if i normally eat 2500 calories or 3000 calories.

Do I need to really really start tracking all of that to get the last 3-5%? Or can I just continue to do what I do, which is behave 6 days a week and do 1-2 cheat meals?

TLDR; 17% BF now how do I get into the 12% range (count calories/macros??)

Thanks guys and although i don't respond all the time, i read a lot of what you guys put out on the board (keto stuff/macros/programs). It's great motivation
