There are no official guidelines on this at all. The usual guidelines just talk about numbers at 90 mins, I think - and you have already hit that target.
I am a little bit precious about fast rises and falls, because I have reactive hypoglycaemia, which means that if I spike too high, too fast, it triggers an excess of insulin, a rapid drop and a possible hypo. This doesn't happen for most people, so unless you have a history of hypos (which you would definitely know about!) you don't have to worry.
So really it is up to you to decide what you want to aim for. If I were you, I would run a few controlled experiments and see how different portion sizes affect you, and if you do better after meals, or with cream, and so on.
At least that way you are making an informed choice, rather than thinking that fruit is 'fine' because it doesn't show up at your 2 hour test.
Hope that helps.
