I'm pretty sure in the more granular data, variability would increase. The reasons I posted the long term graphs was to see if anyone had a good explaination for the almost PERFECTLY LINEAR increase over long time horizons.
There is a standard adoption curve for technologies, methodologies, movements, etc…it looks like a lazy S … not a straight line.
This is creepy…I've got a graduate degree heavy in this type of modeling. This is machine management unless proven otherwise. Some breads will go faster, etc…but human activities ebb and flow over longer horizons…this is perfectly straight beyond all coincidence. Both charts methodologies are sound in my opinion…big samples yield good stats on big populations.
