In parkhomov translated paper, there is curve power vs. temperature, and it has been fitted to polynomial with terms for temp difference and also for absolute temp for T^4. Compared to Stefan-Bolzmann law, there is rather big difference in the coefficient for T^4, is that error or what should the curve look like theoretically? (or actually the area of the object must be used to scale, then t^4 coeff makes more sense).
Tried decomposing the curves:
A polynomial fit It is an approximation, backed by calibration. It is of course not exact and can’t be considered precise as the error bars are wide. But it can be used as a simple and accurate enough energy balancing approximation method when calorimetry is not available or is complex to implement due to the nature of the experiment. Of course this will not convince anyone that is skeptic of the possibility of seeing excess heat, but if you try this method against known heat sources you can fine tune it to reproduce the measurements to a good degree.
The T4 dependence does not fit because the temperature is a single point on the reactor (possibly under a cover), instead of the overall external temperature, relative to total input power. The precise input power to the specific temperature measurement area is not determined.
why not using a non linear regression method ( e^x) for modelling the function? You would even be able to use statistical methods (f-test) to check how statistically significant the modell will be.

What Parkhomov did using Boltzman equation as base was, by his own words, a practical aproximation. That's why the T4 coefficient is not exact to the usual Boltzman equation. Parkhomov says in his paper that he used this ad hoc equation because calorimetry was too complicated. The Equation has a good fit to the calibrations. Of course this method will never be accepted as accurate by anyone that does not accept the possibility of excess heat coming from a NiH system, but Parkhomov is way past the point where he needs to convince himself of this, so he assumes excess heat is possible, and has an equation with a good fit, so he uses it to measure energy.
This will not convince any skeptic, but Parkhomov is not trying to convince anyone, he is just reporting what he is doing.
