> It verifies that the track is under tension, but it doesn't attempt to answer if that tension is "too much". Which is what the question asks.
I think you (and many others in this thread) are confused because you read the title but not the body of the OP. Quoted:
> 1. Is there any way to quickly see if there is any tension, and why? (I know I could just take one piece out, and put it back in to feel it myself, but I am looking for a more logical way, so I am able to reason it.)
> 2. Suppose I want to update the track in the picture to have less tension. If you have to take away exactly 1 rail piece (straight or curved), which one is the best, and why? If you have to add exactly 1 rail piece (straight or curved), what is the optimal place to insert one?
