Backend Instance Hours in Dashboard reflect B1 class?

[Marcel Manz]

Is the 'Backend Instance Hours' resource in the dashboard calculated for a B1 class, as it's showing price 0.08 / Hour ? So in case I'm using a B2 class for 0.16 / hour, the instance hours calculate with twice the speed? B4 four times and B8 eight times? Example: - Using a B1 class with 20 instances = 20 instance hours / hour - Using a B2 class with 20 instances = 40 instance hours / hour - Using a B4 class with 20 instances = 80 instance hours / hour - Using a B8 class with 20 instances = 160 instance hours / hour Is this correct? Thanks Marcel
