In regards to death and wild animals its a fact of nature they live with, I personally don't think it affects them like it does humans. However predicting their reaction to a scent or finding is not possible either. I'm sure we can all tell a story of a deer walking in with your wind right in his or her nose, then others who blow when everything is seemingly perfect and in your favor. One never really knows and what might work once may not work the next time...that is hunting.
About the only worry I'd have about dumping the guts where I'll be hunting soon after would be the presence of scavengers, as this can make game uneasy. However like most stated a gut pile doesn't last long in my parts so if it were a few days I won't really worry about this factor.
No right or wrong method, have to go with what has worked.
