Haha OK. You continue to believe what you choose to believe, and I will believe what I (and medical science) choose to believe. Fair enough.
The studies behind T(lag) variation have been posted on here many times before. But if you can't be bothered to look for them yourself, here's one to whet your appetite:
http://onlinelibrary.wiley.com/doi/10.1111/j.1440-1746.2006.04449.x/abstract
Let me know if you'd like me to point out the relevant parts to you.
"Ha ha" indeed. I am glad discussing the despicable murder of a young girl is so amusing to you. But I will overlook that for now.
As for the abstract you linked to, one point that jumps out at me is:
Results: The mean ± SD of half gastric emptying time (T1/2) of a fluid test meal was determined to be 80.5 ± 22.1 min and for Tlag to be 40.3 ± 10.2 min. However, the T1/2 and Tlag of solid meals did not fit to normal distribution and thus median and percentiles were determined. The median time of T1/2 for solids was 127 min (25–75% percentiles: 112.0–168.3 min) and 81.5 min for Tlag (25–75% percentiles: 65.5–102.0 min).
Yet, your whole argument is predicated on normal distribution. How do you justify that?
And as others have argued here, this was apparently a carefully controlled experiment (although it's hard to tell from just the abstract), with carefully controlled amounts and conditions of eating.
In real life, people eat more (or less) than in an experiment.
How much was eaten in this experiment? I cannot determine that just from the abstract.
Frankly, I find this subject difficult to research as a layperson with a scientific background, because I do not have easy access to more than medical abstracts. MEDline is too expensive for me to subscribe to.
So, please enlighten us with a real argument based on more than just a bare-bones abstract about one 90-person experiment (only 45 women!), eating under controlled conditions, when Meredith was a real person eating under real conditions (probably greater amount, a different type of food probably, and an extended eating period consisting of three main sub-meals: pizza, ice cream, and apple crumble, spread over 2.5 hours, and even possibly followed by another mini-meal of mushrooms and a small glass of beer or wine).
I supplied an abstract which said that you can't use stomach contents alone to determine time of death. I repeat it here:

Abstract
The inspection of the contents of the stomach must be part of every postmortem examination because it may provide qualitative information concerning the nature of the last meal and the presence of abnormal constituents. Using it as a guide to the time of death, however, is theoretically unsound and presents many practical difficulties, although it may have limited applicability in some exceptional instances. Generally, using stomach contents as a guide to time of death involves an unacceptable degree of imprecision and is thus liable to mislead the investigator and the court. [emphasis added]

Did you ever find a reference that refuted Jaffe? I can't remember.
As for the duodenum being empty, Dr. Ronchi said the following (pp 178-9 PMF English Translation of the Massei Report):
Besides this, the alimentary remnants in the small intestine must also be considered, and thus, as hypothesised by Professor Umani Ronchi, it would be possible to think that these remnants could have been found in the duodenum either because of an imperfect apposition of the ligatures, or because of an apposition of the ligatures that took place with such manner and timing as to make it impossible to avoid a sliding of material from the duodenum to the small intestine. The fact [that the] duodenum [is] empty is not [necessarily] fully reliable.
Thus, we are talking of a possible partial emptying of the stomach before time of death.
Regardless, the time of death argument is not critical to the argument for Knox/Sollecito's guilt. They have no alibi from 8:40 pm onward. The computer activity at 9:10 may not have even required human interaction. They certainly have no alibi after about 10 pm if you consider Curatolo their alibi (funny how he's considered reliable by Innocenti when it's convenient for them, and a "bum" that "lies for the police" when that's convenient for them).
Their sole alibi is the girl who wanted to go to the airport. After that, they're each other's alibis. And I don't even remember Sollecito alibi-ing Knox on the stand. Maybe I missed something.
In other words, say they killed Meredith before 10:30 (even though I still don't believe it, because of other evidence). So what. Works for me!
