That is correct. You will name the fraction for this peak based on when the highest point came through. And you got it right. Now, you can name it fraction number, you can name it by time, you're called on to name it by volume, and you can use your tubes for that info. You also seem to be a bit worried about the width if the peak-- where they start or that they've run together. And you can note that information. But you will be called to find peak apex, and you have found it.
Sorry folks, I spell better when I'm not on my phone.
