Thanks for insights, JulianEdgar - appreciated! The idea on that top edge (between side and top surface) rounding is something like that on the Tesla... nothing drastic...

If the edge is top edge is left too "sharp" and as the top surface drops down anyways, air on side wall travels straight (looked from side) while on the top air follows the top surface with higher speed... which creates pressure differential and air movement start to go "up" on side surfaces and over the edge... if I have understood correctly.... Thats what I try to "avoid"...

Example on the Aerolid.... (and copyrights belongs to the Aerolid)...
