scale slider on feDiffuseLighting operates in the absurd range [-1000, 1000] with a step of 0.1, whereas 90% of the useful values lie in the range [-1, 1]. [-5, 5] is a more appropriate choice. (I'll follow up with a ptach that fixes some of the more outrageous ranges.)
You need to be careful about choosing ranges. It is hard to predict what people will find useful. We have in our own preset filters values outside the ranges you have proposed. For example, we have filters with surfaceScale values of 10, 10.5, and 50. I have in my book examples with surfaceScale of 60 and 300.
It is a problem with our current interface that you cannot allow all reasonable values and have the slider cover the potentially most used range. Currently, the only way you can set values outside the slider/entry box range is to use the XML editor so it is better to error on the side of too large ranges than too small.
