I don't think you make anything clearer by translating your intuition's unlikely to N%, while my unlikely is M%, where M!=N. You just make a false impression of having done a calculation (which, unlike intuition, can be confirmed).
Suppose passive_fist translates "unlikely" as 2% and Locaha translates "unlikely" as 12%. This could mean either of two things (or some combination of them). (1) passive_fist applies the word "unlikely" to things that feel more unlikely, corresponding to lower probability estimates when forced to quantify. (2) Both actually think much the same about the event in question, as shown by their use of the same word, but they have quite different processes (at least one of them very inaccurate) for translating those thoughts into nu...
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
