Hey all,
Theres a bit of talk here and there about diagnosis of extraction issues like early blonding and channelling, but it seems like lots of people try to describe their questions and examples. Maybe some videos would work better! I found a few on youtube which I would love your comments and thoughts on what is happening in the each extraction process, whether each pour has issues, what might be causing those issues and how to get a better extraction.
Please take a look and put up your comments your comments or ideas for other CSers and the betterment of extractors everywhere!

In the above video, to me it looks like its a bit of a dounut start, then once it comes to one stream there are little blond "injections" that come into the stream for about a second every ~2 seconds. Is this a problem or normal and to be expected?

This has the title "problem sample" but to me it looks pretty good and even, not having blond squirts like the one above and not rushing at the end. Can anyone else see problems?

Ridiculously thick and massive cone - is this just super fresh beans? What else could cause this and is it a good thing?

This happens to me sometimes - it seems to have some massive thinning and rushing in the 2nd half of the pour - what causes this? Is it channelling?
Please list your diagnoses and also some more videos for other to diagnose as well!
