Hello Phil, Caspar, Tim:

Here is my draft of the text for sections 3.3-3-4. In reality, I left the bit of 3.3 already there more or less as is, and focused on considerations for test protocols and example tests of CFRs for single series and whole-field reconstructions. Let me know what you think.

Note that the added text in the main document is entirely highlighted in yellow. Any place you see red font is meant to highlight a textual uncertainty on my part, including the proper numbering for graphics. I utilized Roman numerals for the time being.

I hope I have hit a correct balance. Note that I focused primarily on the tests I am aware of since and including von Storch et al. in 2004. I purposefully did not focus on the earlier tests with control runs/shorter runs. In terms of the graphics I obviously highlighted the tests that Caspar and I presented last June , but I did mention a number of other tests by various parties in the text. I thought this was appropriate, to focus graphically on the material that was presented last year (plus new material for the whole-field case). I also put in a good bit of material on RegEM along with work on the Mann et al. and Luterbacher et al. truncated-EOF approaches.

Tim, if I have neglicted anything you have done that is relevant, please let me know. I apologise if so, as this would represent pure over-looking of things on my part. I did not make mention of the model-based tests you showed last June, as, according to my memory, these were derived with a <3d model, and thus were not directly applicable to the case of CFR. It was my understanding from the text sent in January that the focus of this section is to be directed to CFR situations.
