Yes, that long run of belt, I would have probably around 10mm of easy deflection in it - you really do not want to "twang" timing belts like guitar strings ;)

As long as they are not flapping in the breeze, the tension does not affect accuracy as much as you might think, but it will wear things out, cause resonance and generally not be good.
