Not exactly. The slope of the input power will become lower as the temperature is increased in the chart that I use. If this slope is not reduced as the temperature rises then there is little positive thermal feedback present. And, if the slope enters into a negative region as temperature rises the device will continue to heat up until it either self destructs or the careful geometry of the design begins to take more heat power away from the system than is added by the core. The new high temperature safe operating region exhibits a positive slope similar to what is seen below the negative slope threshold temperature.

From: David Roberson I would like to see the curve of input power versus temperature plotted. The input power needs to appear along the Y-axis and the temperature along the X-axis. This type of curve tells very much about how the device will behave. It can demonstrate when the COP will become large and indicate the potential for runaway conditions.

A goal of COP=1.5 is in range with only a few more changes. In fact, Jack held back on the hydrogen carrier (TiH2) due to the MFMP “explosion” and therein is an obvious way to look for further improvement. The most notable feature is that gain was seen at very modest P-in which is due in part to thermal insulation. Jones PS – there is a paper in the LENR library by Dash et al where the authors state that titanium is more active for LENR than palladium. Therefore using TiH2 to carry hydrogen, while retaining lithium in a much safer form is almost a no-brainer.
