Not really. You just have to avoid comparisons if the move's effectiveness is going to be defined by stats. That means nobody can go "The shockwave is powerful enough to break concrete" (that depends on their ATK), or "The forcefield provides similar resistance to an inch-thick plate of steel" (that depends on their DEF). For things like projectile size or speed, they're not really tied to anything so they're A-OK for real-life analogues (ex. "Each rock is hurled with the velocity of a bullet" is acceptable).
