The data we have that shows the exponential relationship of xsh to temperature is real and from Mizuno’s experiments. The data I published at iccf24 also showed an increase according to temperature but not an exponential function. This is related to the small surface area vs. the type of calorimeter used we believe. We also don’t have control of all the variable in an outside replication experiment. The reactors under construction now have a much higher surface area and the new calorimeters we are building also will incorporate several improvements meant to get more resolution and faster results allowing us to do more data points in a shorter time span.
Just make sure you are measuring for long enough to rule out Arrhenius like behaviour from chemical reactions: obviously with larger samples you need to measure for longer.
