The English text said every six weeks, which would mean once in six weeks right? Should it not be une fois par 6 semaines?

It seems the speaker is saying "l'impact de gigantesque."  I understand that a "de" here would be incorrect, but that is what I hear.  I presume this is because she is actually emphasizing the end of the word as in "l'impACT gigantesque."  Nevertheless, the emphasis on the end of the word seems over done.  

Later, it sounds as if she is saying "cette décision était facile."  I understand, too, that this would be incorrect grammatically, but nevertheless it is almost impossible for me to here clearly "ait été."  

Perhaps the lesson here is that one should not go by what one thinks one hears, but figure out what would be grammatically correct.  I guess that is probably what we do when listening to English.  We "sort of" listen but actually are just following the flow of the idea being transmitted and fill in the precise details only as needed.  

In the follow sentance someone is reporting back what was said to them. 

"donc, au beau milieu de la nuit tu serais allé boire un verre d'eau et tu aurais vu une soucoupe volante dans le jardin, excuse-moi!" 

Why is the conditional being used here instead of the passe compose. And if I were to speak this sentance using the passe compose would it be incorrect. Thanks.
