Power distribution in a cut

So in this chart, the x axis is the timing of the cut. Left point is the beginning of the cut, and right point is the end. y axis is how much power you put into it, top is more power and very bottom is no power.

In a cut, people tend to insert "umph" differently or apply tenouchi at different points of the cut. These graphs are to help what's good and bad.

Figure (A) - A good cut. This is generally a good cut. The power comes at the beginning of the cut providing tip weight and speed so the sword will have enough power to cut however it trails near the end so the sword won't bounce. This will provide you with "relaxation" to quickly move into another cut.

Figure (B) - Too much power. This cut will probably get through the target (assuming hasuji and posture is correct), however the sword will bounce at the end of the cut, possibly hit the floor if the sword misses the target, or if the hasuji is bad and it clangs into the target, it'll hurt. Also tiring.

Figure (C) - Power is generated too late. This is the most common power curve I see in people. It'll cut with a sharp sword, but if the momentum that has been built isn't enough it'll get stuck. This is usually the result of dropping the sword and cutting too forward and not enough upwards. This also lends to sword bouncing as well. In a sense though, this "timing" of power generation can be used in gekken to build momentum for a second cut while using the 1st cut as a feint. Also this cut also works for when you're cutting when moving forward since the momentum of moving forward can help make up for lack of power from tenouchi.

Figure (D) - Power generated at the moment of the cut. This is usually how I cut. I generate lots of tenouchi right before the cut, and then quickly go dead. This works for me and took me awhile to do. Couple of things you can use for this. Multiple cuts, one technique (inazuma, mizugaeshi etc) This is how you save breath and cut faster for those techniques. In gekken, I use this idea to hide my intentions til the moment of the cut.

If there's something I missed, let me know, I'll add.
