One training period a week for two years equals ok, well maybe ok.
Three training periods a week for two years equals good.
Six training periods a week for two years equals great.
Twelve training periods a week (twice a day with one days rest) for two years equals supernaturally super.
Can't make class twice a day, no worries train your jurus, langkah and forms and hit things. Keep in shape and think about it.
Moving forward with my group, up until now when new people have joined the group we have gone back to the beginning and then started again. I have been thinking about this and have decided that maybe that is not the best way.
In future I will cover each subject and rotate between subjects, so those in the group longer will get more depth each time. We will keep going round and round as we spiral upwards skill wise. Practically the class will look like this, solo training, partner training and free play, then back to solo training etc. etc.
