In reply to Malarkey:
I think you are doing exactly the right thing. I've never seen the app as something that must be complied with.
I've never used the preset programs and only used my BM1000 to develop existing strength and develop my weaknesses. I've just got to the stage where I'm working my back 2 and do this in unison with the deep 4 finger edge.
Keep using that method and those gains will come. Also consider on rock you may find yourself using a deep and shallow edge or pocket at the same time so it has value in that sense anyway.
