On The Level?

The British Heart Foundation publishes a booklet aimed at clarifying the safe quantity of salt we should consume.  I learnt that if a quantity of Sodium is declared on a food product then I should multiply this by 2.5 to equate it to the Salt intake.
However, I did find this picture a trifle confusing.
At first glance this illustration appeared to me to be a heaped teaspoon, not a level one as described.
On closer examination I can see that the spoon is not filled to the rim and the contents may indeed equate to a level spoonful.
I wonder if every reader will take a second look.
