Graeme,
If I displayed more decimals in PatchTool Info window, the
value would be 1,77713345 instead of 1.78! However, even
rounding at 1.8, this would be enough precision for 99% of
uses, maybe even 99.9%, or maybe even... OK, I will stop
here ;-)
What I retain from this is that we implemented the formula
in a very similar fashion!

I opened the text file with PatchTool and compared the
first patch with
the second one, and got 1.78 (CIEDE2000 1:1:1) (Note:
you can do this in
PatchTool trial mode).
I ran the two numbers through Argyll/verify -k, which
uses
a from scratch implementation of CIEDE2000, and it
returned
a value of 1.777133.
