Isn't it amazing? Just one man could fix his open source profiler in just a couple of days after (probably) just one e-mail.
Graeme was very effective indeed and I'm the first to confirm that he made an amazing job.
That said, he can confirm that it was not 'just one e-mail' from my side:
in these days I have tested something like 6 different consecutive beta releases of the chartread exe in the way to support him to iron out the issue, and for each release every time I have performed extensive test, data statistics, graphs and shared analysis and comments, including the ColorPicker comparisons with chartread various modes (strip/spot, high res or not, single or averaging etc etc...).
I'm not here to say that I have big merit, but at least I will let you know that for this task I have involved some dozen of research/test working hours for sure...
In any case I agree with you, it's amazing, I really think that his commitment is absolutely invaluable,
and all the Argyll users should really be very grateful to Graeme Gill for his efforts.
