Keyboards tend to have less steps, such 3 or 4, and then you end up with it displaying 30%, where it really is 33% leading to unexpected brightness changes when interacting with the applet. However, there has been attempts to fix this [2] but I am not sure whether the dataengine supports that now. The battery applet certainly does not honor these properties yet. (I should look into that, though)

If you look at the code, the percent will always comes from dataengine, are you talking about when send value to dataengine, the dataengine will return a different value after actual adjustion?

BTW, for the angleDelta trick, you can reduce 120 to 12 and step from 10 -> 1 to get fine-grained if we don't want 10 as step anymore.
Actually I tried to remove step: 10 in slider, and I can get extremely smooth brightness change (at least my system support it).
