The data was almost exactly the same as before! There was a bit of difference, but not enough to statistically matter. In fact, you could overlay the two paper graphs, and hold it up to the light, and the bars on the graph were exactly the same. There was no difference!
I sat back in the chair in the office, with one graph in each hand. I looked at one graph, then the other. No differences could be detected. I swapped the pages I was holding to the opposite hands. Still no difference.
I looked at the spreadsheets. Double-checked my figures, looked at the calculation formulas. They were correct. I looked at the first spreadsheet. Same formulas on each spreadsheet.
I sat there with my jaw open. (Perfect invitation for a cave dwelling insect to fly right in.) This wasn't right. I was sure that the suspect data packets would show delays. Nope. No difference.
I took a deep breath, and then closed my gaping mouth. ("You'll freeze your face if you keep making those faces!") Perhaps there was a problem in my programs.
I grabbed the program printouts, and spent the next 40 minutes carefully looking at the source code of the programs. No errors, although there were a few routines that could have been made a bit more efficient, those changes wouldn't have affected the results.
Hmmm. Time to cogitate. (I always liked that word. Most people didn't know it meant 'think'.) So I got up from the office chair, and headed for the kitchen. Oatmeal raisin cookies were great for cogitating. I grabbed a couple of cookies from the fridge, and aimed one to my mouth.
And then stood there with my mouth open (again), cookie poised for entry. As Homer Simpson used to say: "Doh!".
