Yes, like Cpadolf said, the key to performing the CWJ is actually to release the forward button for a single frame anytime during the jump. Doing this can bring the odds of a CWJ possibility from nil to almost guaranteed. Amazing little trick, eh?
So I just developed this incredible new Elite Pirate strategy. The only problem is that the x-ray scope is required, and the current 100% run route does not collect the x-ray until the end of the game. I spent some time trying to find a logical means of collecting it early, but in the end it would be slower. Oh well, I guess the application of this trick will never be used in a real run.
Let me explain how this works. I recently found out that the elite pirates can take damage even when they are not in their yellow attack form. When they throw their arms at samus, they are actually vulnerable for 2 frames. If you hit them with a charged/plasma/wave/ice, you will do 900 damage. They only have 1,800 hp, so 2 hits are required. If you turn on the x-ray just after it makes first contact and wait for 10 frames, they will become vulnerable again and a second hit will happen from just the one beam, killing them instantly.
here we go
