Forget what i said. Since you can return your chakra to a previously pathed tenketsu, your first choice would be 1 out of 361, then every following choice would be 1 of 360. Only there is no limit to how many choices you can make for a single jutsu, exept for time/chakra constraints.
not quite as you can't repeat a tenketsu, though you could alternate two of them. so it would be 360^360×361
