you're not really supposed to change the threshold all the time. you're supposed to set it to the lowest useful value, and then use repeated ctrl+l if you need stronger simplification.
i agree that the dependency of simplification force on object size is not perfect. yet i think you will agree that in general, such dependency is necessary. it's just that we need a better and more meaningful way to determine the size of the object for that purpose, taking into account the compactness of the shape. for example a long but narrow calligraphic stroke must use the same force as a short stroke of the same length; on the other hand, a big round lump needs stronger force than a small lump. it's an interesting mathematical problem to develop a measure of size for the purposes of simplifying that would always make visual sense.
