If I got two extremely low club marks from two different games in a short window. I would reach out to the appointments officer and ask for the feedback on the reports. To give below a certain mark - comments are required. Also I would be asking is this something the clubs do regularly.
Eg. If they give out zeros everytime they lose, I would mostly disregard what they say. But if this is their first zero ever, I would be extremely interested in what they have to say.
Look at what the clubs say and if you might be able to improve your game.
Another thing worth considering is the end of fixtures are often extremely memorable. So if you choose to play a lot of (or not enough) extra time. The team that least benefits from this will be annoyed. Especially if a winner/equaliser is scored during this time. Nothing you can do about this, other than factually justify your extra time. This is similar to giving a 90+ mins penalty. Doesn't matter how stonewall it is. You will be marked negatively for it from the non-beneficial club.
