200% stun has better odds of stunning enemies farther from the center of the attack zone. Since this unit has attacks with big areas of effect, that's quite significant.

Usually, attacks are about 1/4th as likely to inflict statuses like Stun and Poison on enemies in the splash damage area (the yellow spaces around the crosshairs). So 100% Poison for a sandworm's spit attack becomes only 25% on the secondary targets. Sonic Boom has 200% base, so it has 50% Stun on the closest yellow spaces, and scales downward in the farther ones.

I haven't figured out exactly how Brown Noise's stun chance scales, but it seems to stay quite high even at range. I've stunned entire Raider and Critter formations with it a number of times.
