A few usage guides still object to the use of comparison words such as more, most, nearly, almost, and rather with perfect on the grounds that perfect describes an absolute, yes-or-no condition that cannot logically be said to exist in varying degrees. The English language has never agreed to this limitation. Since its earliest use in the 13th century, perfect has, like almost all adjectives, been compared, first in the now obsolete forms perfecter and perfectest, and more recently with more, most, and similar comparison words

Love the screenshot!! :)

I'm not sure there is enough time left on the spark timer to do that, also I think the room after is to long

It's not about the charge timer (you have more than enough time to carry it into the next room), it's about the length of the pre-Ridley room. Basicly the rule I figured out is: All rooms that are longer than 2 screen blocks won't allow you to make a distance shot to open the door on the other side fast enough to shinespark through it without hitting (the only exception to this are blinking grey doors, because they open 6 frames faster). As Cpadolf said, the speed of the spark just gets too high after more than 2 screen blocks.

Then run in the pre-Ridley room until it becomes possible? The shot doesn't have to be fired immediately when entering that room. You could try running towards the other door and fire+launch the shinespark in the exact frame where it works.

Btw, some time could be saved in the Ridley room by charging the shinespark in that room instead of the adjacent room

Well I checked and figured you could enter the pre ridley room with ~50 frames left on the timer, in the beginning of the room there is a unavoidable fall (you start without ground under your feet) and no large platforms where you could gain great speed. Thus you can nor make it that far enough into the room, I don't even think you would come very close.
