Fred_BearWhat about when it switches back to down, is that not a kink as well?
b.pickupA flat down flat would be called a flat down flat. If it went flat down flat down it'd be considered a flat to kink rail
b.pickupIt would still be a single kink but if you were to describe it to another rollerblader you'd word it as "theres a flat section then single kink
okay, so here is what OP is trying to say:
as if you were looking at the rail from the sky, only changes in the rail that have acute angles are counted as kinks. any angles over 90 degrees (down kinks to all the skiers) are not counted as kinks by themselves, for some stupid reason. they consider the whole change in the rail (both the down-flat and flat-down kinks) as one. in other words, a kink in the rail is a section of rail that interrupts a rail's general course. therefore, if a down rail had a section in the middle that suddenly went flat and interrupted the normal downward flow of the rail, that would be a kinked rail.
oh yeah, and one last thing:
OP you're dumb
