Go to Build Columns, select Edit Column, Select Power, Notice the data is calculated by the Value of: feature. This means the data is fixed and "hard wired". You can create your own power column by changing how the data is calculated. Try several. Then create a method called Power. Then fill the method with your newly created Power figs. Now backtest to see if your Power columns are better than the canned ones.
You won't break the program.
