The very strong winds on the day I flew the 500 reminded me of the excruciating choices the pilot of a slow jet faces. The wind was blowing 120 knots or so above 30,000 feet so our westbound groundspeed was knocked back to slow turboprop levels. But if we had descended into less wind, the fuel flow would have gone way up, so our range would have been about the same because more fuel was required for each mile. The Eclipse, like other light jets, burns a lot of fuel down low with nearly 1,000 pounds per hour at max continuous power at 10,000 feet. If ATC won't let you climb, or the winds aloft are on the nose, full tank range is not much over 500 nm.
