Thanks to those that responde= d to the fuel question. This is how it was
worded:

There is 30min of fuel in your plane.
You wanta meet your friends for lunch on this stunning VFR day.
You don't have any planned flights for the next few weeks.
The lunch stop's gas is the same price as as at your home field.
The lunch stop's runway is 5,000 at sea level.
The flight time to lunch is 30mins

How many mins of fuel do you add to your tanks for the flight?

Here is the summery in the form of:
in the plane + personal min + trip + extra

30 + top
30 + top
30 + top
30 + top
30 + top
30 + top
30 + top
30 + top
30 + top
30 + top
30 + 30 + top
30 + 15 + full wings, not aux

30 + 30 + 60 + 60
30 + 120
30 + 120
30 + 120
30 + 120
30 + 30 + 30 + 30
30 + 30 + 60
30 + 30 + 30 + 15
30 + 15 + 30 + 15
30 + 15 + 30 + 5
30 + 0  + 60
30 + 60

common notes:

1) always top
2) add enough to get to lunch and home plus personal reserve
3) fill to a level one can directly observe fuel in tank.
