About Stand points # x # ranges

About this topic, when i first arrived on this bot i readed somewhere, that the ranges while adding a waypoint for example 1 x 1.... or 3 x 2 were to get a random coord from the coordenate you just added so it doesnt walk exac same every loop..... is it really for that?

Because on my case its acting "weird" then, it arrives the point but then it walks around the range area, if its a 3x3, it walks in a saquare of 3x3, in place of picking a random point inside that range...

So my doubt is if its a bug actually, or is it supposed to work like that? xD

Thanks
