Cold February day (18f), very clear sky.  SIM expected 4700' but the rocket outperformed about 9% in the cold air.  Rocksim may have over-estimated the impact of the cold, dense air.  The cold did cause a lot of issues with the starters though - it took my rocket 3 tries to light the J540R motor.  Apogee and main deployed nominally.  The rocket landed about 400' down-range just 20' off the path and an easy recovery.
