The two most important rules of databasing are:
GIGO (Garbage In = Garbage Out)
As you put data into the database, ALWAYS remember that putting false or sloppy information into the database will get output which is incorrect, unreliable, and worthless. If you are going to cheat or be lax about putting information into the database, you are wasting your time doing it at all.
Partial data = No data
If you only enter your good sessions into the database, you may be able to use the database to find your strengths, but it will be useless for helping you find your weaknesses. It will also not be able to show you what you are doing right and wrong when you are having a bad day, versus when you are having a good day. Always remember that there are a lot of things in life that you cannot learn by succeeding. You have to record and analyze your failures to learn them. That goes for learning remote viewing, especially.
