Unbending by steps – pick inside radius or outside radius?

The LogoPress help file recommends that when using “Unbending by steps”, you should pick the inside radius. But in reality, it really doesn’t matter which you pick. I almost always pick the outside radius myself, because it is always obviously a bigger target and is always closer to you. But when an unbending doesn’t work, whether you pick the inside radius first or the outside radius, the first thing you should try is to pick the opposite one. Very often times this works.
