Agreed. Though in the latter case you might still do best to give numbers: "Somewhere around 1%, but this is a wild guess so don't take it too seriously." This is not the same statement as the corresponding one with 2% instead of 1%, even though both might be reasonably accurately paraphrased as "unlikely" or even "very unlikely".
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
