The presence of the Yapping Maws causes Samus to immediately lose i-frames while moving; so the damage boosts must be chained directly from one to the next, with the exception of the first. Do the first damage boost from far enough left that Samus can land without bringing the first Yapping Maw on camera; use i-frames to do a spin jump, then chain 4 more damage boosts to cross the room. This can be done by holding jump the entire time, and releasing right at the end of each boost, to fall straight down for the next boost, facing left the whole time. At the end of the final boost, hold left to boost downward, wait for knockback to expire, then press right to do a buffered turnaround spin jump out of the lava.
