funny, i saw this site quite a while back and never investigated further. i think the first spike in the red line is an example of "start up." actually, it would be an example of a very bad case of "start up." the increasing slope of the red line might be a increase in drag pressure because of the decreasing diameter of line on the spool as a fish pulls line out. this would be normal.
a properly functioning drag washer would have little to no initial spike. but what they may have done is to turn the handle with the line tied off to a scale. then what you are seeing is a drag pressure that tripled as a result of heat. been there as well. it's a bad situation. so who knows what kind of el cheapo drag system the red line is.
as far as their blue line maintaining a constant drag pressure, i see no mechanism to allow the reel to compensate for the decreasing diameter of the line on the spool as a big fish takes his run. what they had to do was bolt the reel to a bench with a full spool of line, tie the line off to a fixed digital scale, and then hook up the handle arm to a variable speed electric motor and turn the handle. if the graph is accurate, then it looks like they had a 25% drop in drag pressure over time, probably due to heat. that is not good either.
although i have no data, i believe that a properly greased carbon fiber drag system will give you the same results as the blue line, and maybe even without the 25% fade.
