I did KM for 9 months and was P3. This is with 15+ years of former training. It would allow for fast progression if you could do any of the techniques or learnt fast. So many have left because they just wearnt moving any further. Yet after 1 year away I find I have gone back because no other styles train as hard.
Im trying to get on an instructors course so I can dispose of the politics some what.
And progress further.
