When to use a hay fluffer

I live in east central Iowa.  I have an H&S Tedder / Fluffer.

 

I am wonder when is the best time to fluff the hay after cutting?  I usually cut in the morning and am done around noon.  It usually takes 4 days before I can bale.   I always thought the best time to fluff the hay was the next morning after cutting, but I have been told that advice is more for the rotary tedder than a fluffer.   I was hoping I could get some advice from someone who uses an fluffer. - Thanks
