Thanks @mts , @Rainycatcooks , and thanks all!
I too lose my interest/patience around late February, March.
I have no problem with anything but the body!
It’s a cadaver! It should be fairly predictable. Every dungeness crab has about the same anatomy; the same thorax with the same thin walled cavities, albeit one pattern on the inner part, and a different pattern closer to the legs.
I couldn’t find the picture I wanted, but something like this.
Or this
I’m thinking there’s got to be an ideal approach, perhaps related to being more intentional about separating the legs from the body, so I can get the lump meat out more efficiently.
The part a about 3:18 I AM being patient! 
Okay, I got through most of it.
I think just the right amount of pressure in the right place.
Some claws left. The most immediate gratification.
