Narrative:

For the third time in less than 30 days; I have been flying the korry 4 arrival into lga and washington center has given us a clearance to cross ridgy at fl 270. The crossing altitude for ridgy published on the korry 4 STAR is 'at or above' fl 270. The first time I was given this clearance; we had just briefed the STAR; and I put fl 270 into the MCP and verified VNAV path. As we got closer to ridgy; I realized the aircraft was not descending because the FMS was programmed for ridgy at or above 270. We made the necessary corrections and we were able to comply with the clearance to cross ridgy at 270. Since that first encounter; I have now had this same clearance given to me two more times. If washington center wants aircraft to cross ridgy at 270; then the STAR needs to be changed to reflect that expectation.
