like/dislike was meant generally
sure (been ignored several times before Joe), consider °C/W:
for each method, what is the capability of the temp measurement (spec the req instrument) ?
ditto for the power
measurement ?
ditto for the mounting variation ?
consideration of the above will define the preformance capability of the test platform, NOW the platforms may be reasonably compared
repeat for cost,
with such descriptions a prospective tester could understand the cost of accuracy, while a reader of test reports would have an insight into the credibility of test data (or the conclusions)
