Hack motion benchmark for bunker shot

I recently purchased a Hack Motion wrist sensor and found it very helpful for my full swing. I struggle a lot in the bunkers and I think the Hack motion would be very helpful in seeing what my wrists are doing in the swing especially at impact. I don't know though what a pro bunker swing looks like flexion/extension graph wise in the bunker and was hoping someone might be able to help me with that information. Attached is a screen shot of a decent bunker shot I made and it seems I should be more extended at impact. However on swings that show the club extending rapidly at impact I tend to skull them. It would be helpful if I knew what a good bunker graph looked like.
