Samm,
I think we all see your point, but let's be constructive here. What do you want HTC to do? We all see that the representation of the concept does not suit your taste. How do you want this changed?
This is the way I see it. Fuel supply at the base is not a physical volume. If it is we should be talking in terms of liters and gallons. Fuel supply at the base is how much maintenance the base can give to your plane. The base is like a factory churning up supplies for your plane. Depending on the status of the facility on the base, it will limit the fuel you can carry on your plane or give you drop tanks. The "125%" you see represents the status of the facility on the base. At status 25% the base can only supply you with 25% of the internal fuel tank of your plane. At status 50%, it will give you an option to load 25% or 50% of your internal fuel tank. At status 125%, you now have a choice of 25%, 50%, 75%, or 100% plus drop tanks.
The percentages used (while it may be confusing) does not represent the same thing which you are claiming here. One here is not volume.
Is there something wrong with the way this is represented in the hanger?
Is there something wrong with the way this is represented to say the status of the base in terms of supplying fuel to your plane?
I don't think so.
To help HTC, please suggest a way to change this representation so it would be less confusing for you.
