Rule 1: For an N-roll position, the EPC is 7N + 1.

This position is a bit worse than a 5 roll position. If it was a straight 5 roll position the EPC would be 7(5) + 1 or 36. Depending on how well you can estimate how often it's a 6 roll (epc of 43) and a pure 5 roll you should pick an epc somewhere inbetween there. 38 matching GNU's estimate seems right.

Rule 2: Nice positions waste 7 pips.

Even though Blue has 8 checkers off here the wastage won't be much lower than 7 pips. How to know that? Once you look at many such positions you get a good feel for how much these standard looking positions waste. I would have estimated this position still wastes ~6.5 pips so the EPC would be 35 + 6.5 or 41.5.
