Hi Duncan,
Great questions and I can share what I understand and how I practice.
Step 1
Ki3 & CV12 are retained until you see a change in the pulse – usually 5-10 minutes as a guide – can be shorter or longer. Use the pulse to guide your treatment
Liv14 is twist and out…may need another go if you felt it didn’t take…
Lu7 same – flying technique, out…
Again let pulse changes guide your decision making moment to moment…
Step 3
The intention is to block the pathogen from going into the deeper channels and so it can only go out.
Generally even technique and retained for the duration of the sinew release.
If treating Bladder sinew when the patient is lying face down – then in and out on – do not retain – confluent points.
As for all treatment keep clearly in mind what the intended purpose is at each step what you’re doing, then let guidelines and your own intuition guide the process.
Other steps sound good.
Hope this helps.
Kindly,
Hung
