I would be in interested in the CG of the aircraft.
From the report, the nosewheel never touched down, but the tail struck the ground twice.
Also, I'm not sure these were "bounces" as we typically think of them - the aircraft reportedly bounced 8 times in 95 m, so the bounces can't have been very high. It sounds more like skipping along, not quite in full contact with the runway. If the runway has undulations, and you have the nose in the air and some airspeed that might be hard to avoid.
