The formula you've shown is a general guide. Most members on this site would advise you to probably try a higher protein intake than that per day.
With that being said, the only way that your analysis will be confirmed is if you eat how you have planned and monitor your own progress. Some people (most people) will come in here and tell you that you should probably get more calories from protein and less from carbs'n'fats. If your system works for you however, then fuck them.
