Wot no Gas Balance Alert

The interesting thing about yesterday and today is that at times when short term storage has less than 2 days above Safety Monitors then there should be a gas balance alert when the amount of gas used is above the trigger.

The trigger is supposed to be calculated on the basis of what gas comes from sources other than short term storage. However, we are below 2 days and gas is being withdrawn from short term storage.

Hence there should be a GBA, but there isn't.

Luckily the weather looks good enough ... just about.
