Those numbers should be right about what you'd expect.
> Meat and poultry are composed of naturally occurring water, muscle, connective tissue, fat, and bone. People eat meat for the muscle. The muscle is approximately 75% water (although different cuts may have more or less water) and 20% protein, with the remaining 5% representing a combination of fat, carbohydrate, and minerals.
The protein/fat balance should be expected to be a bit off from straight muscle cuts, as it's typical for a burger to have fat added to the mix in.
