It would be really nice if we could ignore records below a certain threshold in both the 1:1 and 1:N matching and in all instances. The current feature in 1:N seems like a great idea, but it doesn't work. It will only ignore records below a certain threshold if there are records that are higher than that.
For example, my threshold is set to 72% on one of my formulas. It doesn't work on 1:1, only 1:N. And it only works on 1:N when there is an 87% match that pulls in at the exact same time. Otherwise, all of the 71% or 50% or whatever matches come through as they are the "highest" and so the system ignores my request to ignore those.
