A question about energy form

[com_easy]

At the energy form, holding down mouse button 2 for several seconds then release it, I can lanch 3 homing missiles. But sometimes I was able to lanch FOUR missiles at the same time. I just wondered how it works. What can I do to make sure that every lanch has 4 missiles?

Releasing the charged shot while standing still or swimming normally spawns three shots, shooting while boosting away from a wall (space or clicking away from Naija) spawns 4, and shooting while boosting away from a wall, then hitting space while making a wake (boost twice) spawns six shots.

[EDIT]: Sorry  for the confusion.

Excuse me?

How to do the "somersaulting"? And, I just tried shooting while boosting, but only got 3 shots. But, shooting while boosting from a wall successfully made a 4-shots.

Boost from wall = 4
After the boost from the wall and clicking again shortly after = 6

Just keep buttonmashing when you zoom away from the wall until you start circling in the water, then release the button to let out 6 tendrils.
