Are 'Single 180 Turn From Downwind to Final' and 'Stall-spin on Turnfrom Base to Final' mutually exclusive?

Define "coordinated". No problem to spin with the string perfectly
centered.

It's true in any glider with enough elevator, but the Blanik is
excellent for demonstrating it. Shallow turn, very graaaadually slow
it down, maintaining constant bank angle with aileron and keeping the
string in the middle with the rudder. Pretty soon you've got a whole
heap of out of turn aileron and into turn rudder. But the string is
in the middle and the nose isn't even very high. And then BAM full-on
incipient spin.

Bruce describes how I practice incipient spins in my ASH 26 E (also the
way I practiced them in my ASW 20 C). One moment I'm doing a smooth,
coordinated turn; an instant later, the inboard wing is rotating down -
no warning.
