A solid burl can be imagined like cauliflower, growing out from a point, spreading in a cone, and finally flaring out and perhaps encompassing the tree. Those are mostly predictable, and a matter of deciding what shapes you want.
This piece isn't a solid burl and thus all bets are off. You have some central damage/rot and won't know much until you get cutting. Often pieces like this don't yield much relative to the overall size. They can be a fun puzzle, but In most cases I've found that being aggressive and 'getting to the point' gives the same result. Much depends on how tolerant of voids and punk you are.
My basic approach is to make useful looking chunks and get them between centers to visualize properly.
