I don't know why I didn't think of this sooner, but now, with the new True North, there is no reason any NIN should ever miss TA. With a 45s CD per charge, NIN will always have at least one charge available to use on TA. SAM goes through it's combo roughly once every 15s on average. With an uptime of 10 out of 45s this means SAM can get 2 out of 6 positionals for "free" via TN and then has to shift position to land the others. No NIN should ever miss TA with the new True North. It would take someone purposefully going out of their way to blow TN charges and then screw up TA in order to "miss" it.
