I know that I am guilty of not adding to the reports section, as I should. I take this view, I learn from others, so I also should share accordingly. However, it's a personal thing.
When I used to publish more reports, I tried as best I could to be as detailed as I could - although, I typically did not give gps coordinates!
If you are preparing for a tourney, I certainly can see not wanting to share info. However, once the tourney is over, I generally post up both what did and didn't work for me.
Basically, you can give someone the coordinates, the bait, technique used, etc. - and that doesn't mean that they can duplicate your success.
