Yes, but why repeat 0 while going from 0 to 10?

For example, if you want to go from -10 to 0 and then from there to 10 you would get something like:

... -3 -2 -1 0 (pause) 0 1 2 3 ...

here 0 is repeated, something that i don't find very practical.
I could always use a [change ] but then again there would be a time gap, wouldn't it?
