For example, you can use the power captain chip in a matchday where you will be unable to actively manage your team. Because of lack of time you activate you power captain and let it do its job.
But for more active fantasy football managers, the best time to use power captain will be on a matchday where: Captaincy is unclear and you are not sure which players from your team are the best captaincy options. There are just 2 days in a matchday so you cannot switch captaincy so often as in a group stage.
Because of that, we think that the best time to use power captain chip is in semifinals or in finals, where are just 2 matches and low points potential, so you cannot really predict which player from your team will score the most points. The power captain booster will sort it for you.
