Am curious, why is the 2 hour post meal figure seen as the standard for measuring a number for postprandial? Why not for example, 1 hour?
 
It has been a recommended standard for a long time but I can't remember who recommended it. It is not set in stone and many people take multiple readings, tighten up on the 8.5 mmol/l figure and generally set their own standard.

If you want to set a target for one hour then feel free.
 
It varies between people, it varies with food and food combinations, but in general there is a peak in blood glucose after about one hour and a return to near normal after about two hours. If you are not going to use continuous BG monitoring then to have some consistency, measuring two hours after meals gives a good indication of your reaction to particular meals.

My postprandial reading, 2 hours was 7.0 which I thought was a bit high for a non-diabetic although it does still fall under the normal parameters. Also this was the number after I had after my breakfast which was around 80g of carbs of high GI food (3x weetabix, milk, some sweet oats - not much sugars though). I figured because of the high GI, is it possible that I could have peaked later as it's more of a slow release?

You have GI the wrong way round, lower GI foods affect BG later. Glucose has a GI of 100, Lentils a GI of about 25.
