Demand formula

[skifans]

OK, I have placed a few more flights just to spam them onto the Geneva to Jersey route. For base passengers this has:
— Base Passengers —
Economy: 162
Economy plus: 23
Premium economy: 21
Business: 6
First: 2
Which seems reasonable, but im now at 8 flights and the competition factor only has the following effect:
— Competition Factor (8 flights) —
Economy: -8
Economy plus: -1
Premium economy: -1
Business: 0
First: 0

Im potentially wondering weather or not this should be nearer to 10 times more then this, how much of an effect do people feel that this should have?
