Hi Daniel,
I believe I have found the key to resolving the Mpemba effect. I see that you are quite dismissive of its existence. I would advise against this. I think there is a flaw or shortcoming in the traditional understanding of hydrogen bonding and Mpemba effect is evidence thereof. Another anomaly, one that is kind of similar to Mpemba, is Non-Newtonian fluids. But there are many anomalies associated with H2O, as I suspect you know.
I believe hydrogen bonding has been systematically misunderstood in that the relationship between the strength of an H bond and its distance has been assumed to normal when actually it is inverse. I have written a paper on this. Here are some links if you are interested:

or

BTW, I'm not saying that I have fully resolved the Mpemba effect. That would take some doing. But I am saying I have found the key that will eventually, either by me or somebody else, lead to its resolution.
If you'd like an MS Word copy that you can print out just drop me an email:'

"Such theories have not been accepted by the scientific community as far as I can tell. After all, they fly in the face of the basic laws of thermodynamics."
You are being dogmatic and stubborn. Consider the possibility that there is something about H2O hydrogen bonding that you don't yet understand. Stop meekly hiding behind what you know and start boldly embracing contradiction. That is where the discoveries lay waiting to be found.
And stop wrapping yourself in the flag of the, "scientific community." It's arrogant to suggest that the scientific community is the end-all-determinant of scientific truth. Some of the greatest scientific truths were first revealed when fractions of evidence that didn't quite fit with the current model kept popping up, irritating everybody. These slivers of contradiction eventually grew into the doorways to new understanding. This has happened over and over again.
Mpemba effect is subtle enough that it can be easily dismissed by people that stubbornly cling to the notion that they got it all figured out. But here is some evidence that even the most dismissive, arrogant know-it-all cannot easily dismiss. And it is the same mechanism as Mpemba:
