>>>Do you think it would be better to calculate this value "on-the-fly" instead of relying on the program updating it?

>Depends how long it takes to calculate and how frequently the value changes! If it's quick or if it's not time-sensitive, then it's better to calculate as required. Otherwise you might consider using triggers to update the value so it can't easily get out of sync, or a separate scheduled process that regularly recalculates and updates the value so that errors quickly are corrected.
Thank you.
