Max tenuifolia seems to do this to everyone doesn't it. This whole difficult to bloom thingy.
I'm still waiting for mine to make a miraculous comeback from damaged roots and start blooming already.
I can remember when I was a rookie with orchids and this happened to be one of the first group of plants I got. Surprisingly it bloomed for me without me knowing diddly squat about it.
Man, I miss that coconut odor and the awesomely unique flowers.
Even though it was a happy accident yours bloomed. Good form and good growing, man! Keep it up.
