Procedure
Aircraft meeting the crossing restrictions on the DSNEE arrival. I have had many issues with aircraft from the north meeting the restrictions but today while conducting my 2 minute overlap in the HEMR position Aircraft X checked on from the East and the first thing the pilot said was that it was difficult to meet the restriction from RHODE (17;000-FL190) to PHIYA (at or below 13;000) which forces the pilot to descend at least 4;0000 feet in 11 miles.
SCT TRACON Controller reported it is difficult for aircraft to meet the PHIYA crossing restriction from RHODE on the DSNEE 1 Arrival which requires a 4000 foot descent in 11 miles.
