You'll notice one has sharp little spikes rising from the graph at the time we're interested in. This graph is sampled at only 120 second windows. The other is the same composite graph with a 1200 second window. That one widens out the peaks so there is a wider overlap, and the "thin peaks" (wasn't that a TV series?) blend into the others. To see a good description of what I termed the "bell-curve fit", you should view the RPKP Probability and Statistics page. I call it a "fit", as you basically take the expected value (probability) and measure the deviation of the actual data from the actual bell-curve. So maybe I should call it a "deviation" from the probability bell-curve. I am rusty on my statistics terms. > A "raw" look at it would make the naive observer think that > single large spike in the middle is the most important, but > I think your "multiple spike" criterion is much more > meaningful.

Actually, when it all comes down to it, these graphs seem to be just graphical representations of your "Extrema by Egg" table. Sure, it will integrate multiple "extrema" into the chisquare calculation, but I think each "peak" is easily attributable to a single extrema. Here are the bitsums responsible for the peaks in these graphs... Egg Time Value ---- --------------- ----- 102 6333 [03:45:23] 128 102 6732 [03:52:02] 128 1000 6669 [03:50:59] 131 1005 6542 [03:48:52] 70 1021 6552 [03:49:02] 131 1022 6824 [03:53:34] 130 1022 6876 [03:54:36] 131 1027 6757 [03:52:27] 131 Another reason the peaks look so nice and uniform is that most of them are 131s, so will be the same amplitude. I'm not saying this is good or bad, but here's what's (mostly) causing what we see.
