I can see what you mean and there is definitely some density issues. I feel like this may have also contributed to the hairline looking slightly"off". Sorry to see you are unhappy brother, I cannot imagine how frustrating it must be.
On a more positive note, you have really amazing hair and I'm sure if you go and see someone else (please find a stick and place doc) you will have a truly incredible result.
Welcome aboard mate. There is plenty of information on the forums for you to research that can help with the above questions; So I would start there.
Also, you need to be aware that it's not cool to hijack someone else's thread and will likely not get you the type of helpful response you desire.
My advice is go and do a few hours research (minimum) on the existing threads and then come back and start your own.
No he extracted around 400-600 grafts per day and had around a 20 min break before implanting. I believe his method is to not put too much shock into the area in one session, and let the scalp recover a little before repeating this process. The only downside to spreading the procedure over multiple days is the dam anastheic injections every day as they hurt like a bitch! Even more so when your head is swollen from the previous days. But makes perfect sense from a medical perspective.
