this is about the worst playing humanly possible because i'm at the wrong house but whatever this was just played to demonstrate the sequence

sequence: ch6, PSD/P | PD/P | I-PPdd | I-Pd/P ( 6 | 6 | 12 | 12 )
The first ice wave can play PD/Pd if you want but it's just easier to shoot in the back
adjacent ch6 doesn't need any pre-placed ices assuming you start with the two non-ice waves.
Also the original ch5 sequence doesn't defend the ice at 3-9 from jacks and it's more difficult so this solution is just better in every way

I would put this level 4 on the skill standard
