Well first of all, it's only been 4 days. Google's index fluctuates considerably when new pages that are relevant to a particular keyword are introduced into its index. It's called a "Google Dance", where so many pages are suddenly indexed that Google doesn't know what to do with them. So yes, you'll have lots of pages indexed, then suddenly very little, then suddenly quite a bit.
But second of all, I just looked up your order under Google's Blog search function (the left-hand side of the screen when you go to google.com, you may have to click More to see it) and I'm seeing 375 results. Try to remember that your links were posted to blogs, so you'll be showing up under the blog search as well as the "Everything" search.
I have interest in your service. I am interested in how many of these sites have pr, have any idea how fast google indexes these articles. How many domain / Ips are with package A .. Do you have category - Health?
