Without going into a rant, percentages mean nothing.
If you eat 250g protein, 500g carbs and 100g fat that will give you one % group.
If you eat 250g protein, 400g carbs and 100g fat that would give you a higher % protein diet.
Macronutrients should ultimately be estimated from bodyweight, (except fat because they have never really shown any decent information for that).
Get ~1g/lb protein, get at least 25% daily energy from fats and just use carbs to bulk up the rest. Possibly 4-5g/kg LBM.
