MR DUBE
I will try and respond to your question in the following ways.  Firstly, I had many cells so it depended entirely on the amount of the workload that I had at the time.  Secondly, when I was involved at the initial stages of training I made sure that I was with those trainees every day so I cannot give you a specific answer as to how often, or how much time I spent with them.  It depended on the situation.
