The Canon Focus bracketing feature operates from a near start position and bracketing towards infinity with a defined number of steps and a parameter called focus increment.
The focus increment parameter is not defined but is understood to relate the focus step value to the current depth of field.
This resource includes results and analysis from tests to reverse engineer the focus increment parameter in the close up range (magnification of 0.1 to 1x) and an Excel spreadsheet for calculations based on this.
