CFI hometime

I was wanting to know if any drivers know how long CFi requires you to be gone....i was under the impression that it was something like 10-14 days with 2 days off...but when i went to my school to send out more info to companys i was told its 3-4 weeks ...anyone know the truth to this question

 

I havnt worked with CFI for a few years but it seems I remember they wanted you to be out 14 days then get 2 off, But that wasnt written in stone. I worked there about 16 years and there was a different President at that time..
