Are you sure ??? Should it not be the other way round ?? Col = P&F. If I have your attention, do your Renko bricks repaint or have you done a workaround to fix this problem. ATR is a good way to fix renko box height. Also there will be a problem back testing standard renko because on reversal, the reversal bar open lines up with the previous bar open. You will need to have an option for reversal bar open to match previous bar close.
