Looking at fig. 4 at

I still doubt that the De Witte results would be so simply dismissed.
The experiment started on early June and ended on late November, and the 
temperature cycle over such a period is not a ramp, still having to cross the 
warmest months before starting to drop.
The De Witte cable was buried, but how deep is not mentioned.
I would see the experiment repeated.

It's a simple mistake we all make at one point or another in our time-nuts 
career.

you happen to pick only half a year, starting early summer as he did, you get a 
slow ramp.

were wrong. Unfortunately he died shortly before I could email him about his 
methods and raw data. That was, what, 15 years ago.
