The biggest problem I see with the timeline has to do with the pineapple. Even allowing for wide variances with known cases for her weight, the room temp, etc. the latest she could have died was 11 p.m. That's from a convergence of TWO well studied forensic pieces of evidence. Now, add the pineapple. She needed at least 1 hour to get that down to it's observed transit point. But that means an intruder had to feed her pineapple no later than 10 p.m. But that's when they were walking in the door. Unless someone can explain that to me, I can't see how an intruder did this.
Your view is too narrow, just in my humble opinion.
This info that you have, as vital as it seems to you now, lacks perspective.
Don't get me wrong, you've got a lot of info about this and have reasoned sharply about a lot. However, the info is not 100% complete...there has to be other pieces of info you don't have or haven't looked at in a broader perspective, that would eventually play into the pineapple thing.
That's why we have prosecutors and defense attorneys and expert witnesses and scientific analysis and oral argument and investigative reporters on both sides of a guilt-innocence issue.
If someone else wants to engage with you about the "pineapple problem", based only on what we think is known about that issue right now, more power to them.
I'm not the one to do it.
I checked to be sure about body "smell", which police reported when her body was brought up from the basement. The time it takes for that, depending on humidity, temp, body weight, etc., is 24 to 36 hours. Merging that with the rigor, the time of death was almost certainly very close to 10 p.m. (my understanding of time of death is that you are supposed to merge information from multiple observations b/c of variance - which is what I've done here). With the GI transit for the pineapple, the consumption of pineapple couldn't have occured any later than 10 p.m. That's even if we break with the forsensic constraints. This is the same time the Ramseys walked in the door. I'm puzzled as to how an intruder fed her pineapple then killed her literally within minutes of her walking in the door. Either there is something wrong with the forensics or there was no intruder.

You are hung up on time when the Boulder ME states "I consider estimation of time of death to be an interpretive finding rather than a factual statement,'' Meyer explained in a prepared statement that accompanied the report. http://www.denverpost.com/news/ci_4191245
They got home earlier than that. The 10PM is an estimate of the time Patsy went to bed, according to John Ramsey, who said he was still awake at that time.
