I'm off the ground within 1000' when DA at KAEG is 9k'-10k'. Climb rate is ~700fpm while keeping airspeed well over Vy. I've taken off from Telluride when the Density Altitude was 13,500 with 2 adults, 2 children and all associated luggage. The ground roll was ~1/3 of the runway and the climb rate was impressive.
Sorry this is more qualitative than quantitative, but it's at least a data point.
