Warning: a controversial opinion is about to be expressed.

This is why DILD is not a good technique; the successes are so rare that it's very difficult to learn what really works. It's like learning to ride a bike by being dropped on the side of a mountain. Like, you ate cheese that day so now you won't get a DILD. This is NOT how you learn.

WILD is much better precisely because it's so much more under your control. More control = faster learning.
