iirc back in Early Days some people did test for it and it was found that it is not a linear relationship between dragon level & impact on dominance when exalted, being more exponential favouring higher levels?

This is all knowledge I stumbled into back in '13 from someone fairly shady tho who asked me to not tell anyone who told me and why, but they told me because we were discussing dom strats and I was theorizing where best to focus effort (ie. where is the cost/benefit vis a vis exalting) so they might've just been sick of me
