Now I better understand why this landing goes far away. The approach speed 60 kts is correct. But to accomplish landing distance of 454 meters, specified in the Performance section of AFM, you need to have idle power at 50 ft AGL - with full flaps you have +22 kts margin to stall speed. From that point (typically treshold at correct glideslope angle), you can expect 226 meters to touchdown and 228 ground roll to a full stop (with brakes). Here, I bring the plane to ground effect at 60 knots, and then reduce power and bleed off the extra speed in level flight, resulting a long float.
You can approach with the DA20 at about 50/55kts and as soon as you approach threshold set power to idle. This is like a glider. Also your aiming point was way off, you should pick a point and fly to that point controlling speed with power. But good landing anyways, lucky you have such a long runway, over here in Switzerland I have 600m and you have to touchdown before 100m marker or automatically go around.
