Do you by any chance know the most technically difficult singles program ever performed? (men's and women's) Is it just the current record holders'?
If by “most technically difficult” you mean “highest base value”, then no, definitely not the current record holders. They got those world records by being clean with high GOE and high PCS, not by attempting the hardest layouts.
Square brackets indicate layouts that were planned/attempted, but were not executed cleanly. * indicates the current world record.
