Actual target altitude assignments on import of the .fms file:

R14: 1335
alt 1800:2100
int: 4000
OED: 7200
CUTTR: 17999  (show alt restrictions between 10500-17999; in reality it is MEA 10500 northbound, but the limit of 17999 appears to be because it is a waypoint on IFR low charts; IMO there should be no upper restriction here; note LNM also shows this restriction.)(?)
RENAA: FL 340
BTG: FL 340
PTERA: FL340
TOD: FL 340
KRIEG: 6000 (MEA is 10000)
HAWKZ: 6000 (crossing restriction is A12000)
LIINE: 6000
PIKEZ: 15000  (A12000/B15000)
COFAY: 6000
BREVE: 11000 (A10000/B11000)
NETTZ: 6000 (A8000)
KWEST: 6000 (A7000)
VASHN: 6000 (6000 hard)
KSEA: 432

The database seems to have the crossing altitude restrictions right, but P2ATC seems to only respect the Below constraints (if started out above, it will go to at least the below constraint).  If there is no constraint, it seems to pick the hard altitude at the end of the arrival.  (In reality wouldn't the restriction on COFAY be A(min(prev.waypt,next.waypt))/B(max(prev.waypt,next.waypt)) ? Above constraints aren't respected at all, and it doesn't seem to interpolate the target altitude for a straight line distance between the two waypoints which is what I would expect.  I can't seem to override the target altitudes.  When I do, it just goes and lighlights the "alt" line above.

How can I fix P2ATC to get a better descent profile?

Another example:

On BRIXX4 arrival to KSJC between CORKK and BRIXX.  BRIXX has a hard altitude of 12,000 ft and a hard speed of 250K.  Yet, ATC says "maintain 17000 feet" (needless to say I was already well on my way down to 12,000)
