Local MQTT Data Definition

     "import": {
       "cumulative": 201.95,
       "day": 1.05,
       "week": 0,
       "month": 0,

I note from the Blog, the sample data above.

If Day is 1.05, why is Week and Month not the same?

What is the definition of the value in Day, Week & Month? when is the start of the week 😀.

This probably needs a published technical spec, please?

Weeks start on Monday (1am at present due to BST midnight during GMT)

This is real data from my meter installed this week at just before 1pm BST
