In looking at tripods I have noticed that there seem to be no objective quantitative measures on their performance. I do understand that heads are a personal preference, but I would expect there to be some sort of stability measure for the legs. Even for the heads I would have expected some sort of measures like smoothness, fluidity(?).
The only numerical measure I have seen so far is that in general more money is supposed to be better. I do not like this measure because it is trivially gamed.
So my question is: Do there exist objective measures of tripods?
