Thanks for answering Shonen. Techniques that use 16 RU are rare and immensely costly, most skills and techniques in canon do not enter that range, I suppose I shouldn't have posted examples in this case, since it appears to have lead to more confusion.

In regards to how Grandmasters and Masters can put out even more power for higher efficiency, I HAVE taken that into account Shonen. Since the central idea is while the energy drain is the same in most cases, the sheer magnitude of the attack might differ. I mentioned that the technique classes used were the base ones, before any changes are made. A Hakuda Grandmaster could use Ikkotsu at the cost of 1 RU, while still having it be much much stronger than the version used by your typical Hakuda Master.

Finally, your way of using Hein would not be an issue, because as Reiatsu is produced by Reiryoku, it is quite efficient if he relies on it. I imagine that most of his attacks would fall into the Basic, Ordinary or Potent range; which allows him to fight for extended periods of time regardless.
