Maybe I'm wrong on the black field part (probably confused it with a body of water that takes in heat during the day and then releases it later), excuse my knowledge as I haven't been reading up on that stuff for about 6 years or so.

Yes 75ft is well above any ground effect cushion. The aircraft is low-performance, a long take off roll is likely the norm in high temperatures. The angle generated by the cockpit video is quite misleading granted it never looks like they achieve 75 feet but according to the release they reached that before encountering what they describe as a downdraft.
I would suspect during the takeoff roll/rotation everything performed normally or you are right he would/should have aborted.
I wouldn't pilot a lawnmover powered aircraft so your question about the takeoff roll isn't applicable. As stated above a long take off roll (by your estimation) is likely normal for this flying chevette with two grown men in it.
