| The total percentage of the poor performing minutes with respect
                                to the total minutes the user spent on all Zoom calls that he/she
                                    attended. A poor-performing minute can have multiple root
                                    causes, so the number displayed in this column could add up to
                                    more than 100%. For example, if a poor performing minute has two
                                    root causes, it will be counted as two separate
                                minutes. |
