Triangles can be drawn in different ways... haejins are often very long and then in perspective, look deceivingly short. There's also always different ways to lay down the waves, here's different examples.
Haejin's triangle is the violet one, his waves the orange ones... more or less.
That means we might be waiting for another week till EOS lifts off, if the market still exists a week from now ;)
