An interesting system to be sure, but I do sort of appreciate Dal's percentage system. The two can easily be combined. If you have Immense Spiritual Power at 48 and start at 100%, then gradually if you used something with 8 RU you would be at 84%, and so-forth.

Perhaps this shows you where you might need to alter your system N. Stating that a guy with Immense Spiritual Power is going to be drained 16% simply by using ONE technique... does not make a whole lot of sense. This seems to be a very heavily Kidou-based system, but in other sets of the Zankensoki, or even say, Arrancar techniques, we have seen multiple characters draw out fights for extended periods of time using several different techniques. Not the best example since it's Ichigo, but I look at the fight with Grimmjow to be an example here. He used Resurrección of course, then pulled out a bunch of bala, hand-to-hand techs, Sonido, las garras etc. etc. Of course, ultimately Ichigo did win, and we could say it was his Reiatsu > Grimmjow's Reiatsu.

But what I don't think you are taking into account, aside from a brief mention that a master is able to decrease the RU of a given technique, is that a master or a grandmaster in a particular area would be able to use techniques much more fluidly and at much higher quantities than your typical practitioner... and their techniques are no less dangerous or "decreased in RU." Take Hakuda for example. If we have a true Hakuda master in the ring, they should be able to pull out a lot more of these techniques because half of the skill is derived in a physical sense: the way you move your body. Which is perhaps where most of the RU expenditure would go, not in the actual techniques themselves.

Perhaps what we need is just a better idea (outside of Kidou) where the ranges for RU fall for techniques here.

On a personal note, this system would present a very large problem to me for several characters. Hein, for example, fights almost exclusively using his Reiatsu as a weapon itself. If I used this system he'd be crippled shortly after releasing his Shikai. So like I've said before, I don't usually consider the "RU number" for the techniques themselves per say, as much as I look at how many techniques my character has used in the RP so far and a "more or less" range of how much Reiatsu it would require. Takashi cutting up an opponent 6 times, for example, is not going to require that much Reiatsu since he relies on bare-bones Kenjutsu, and he's a swordsman master anyway. Of course it would be a different story with Shunpo or Kidou, but hopefully I've made my point.
