In practice, quality is more important than quantity. To defeat a single opponent this is the corret method, to defeat many opponents, this is the still the correct method. The one who practices too great a variety will become panicked and distraught, if one does not train the body with a realistic foundation, in combat there will be no mature technique to fall back on, one will have neither a well trained body nor a solid technique.

So I really like that term mature technique. To me that means the principles of the technique are wholly understood by the practitioner from many directions and with many levels of force, that the body that will deliver the technique is able to do so without hesitation, and that the mind of the practitioner is so at ease with the technique that it can be delivered without thought.
If I think about what I know in this fashion...there is much training to be done.
