In the procedure to get the ideal impact range in the zoomed mode, a fixed minimum probability is assigned. This causes a problem once all the probability differences are below the set threshold.

Do these the zoomed range list get empty:

Now the question is how to deal with this case:

• Should the the probability threshold be dynamically lowered (e.g. by 1/10) until the list is not empty?
• Should we report the full figure instead?
