Chance is not the same as payoff
CRIT Rate is the chance for an eligible damage instance to score a critical hit. CRIT DMG is the additional damage of that result. For an ordinary hit, 150% CRIT DMG makes a critical hit deal 2.5 times its non-critical damage, with other factors unchanged.
A large CRIT DMG number does not make critical hits more likely. First establish that the damage source uses ordinary CRIT rules; a separate reaction or kit-defined exception may not use the Character’s displayed CRIT stats.
Average damage combines both outcomes
For ordinary CRIT-capable damage, the average multiplier is 1 + CRIT Rate × CRIT DMG, with percentages written as decimals. At 60% Rate and 120% DMG, that is 1 + 0.6 × 1.2 = 1.72. This is an average across outcomes, not a guarantee for each hit.
A 1,000-damage non-critical hit would therefore average 1,720 under those assumptions. A small sample can differ considerably. Compare like-for-like attacks rather than treating one large critical hit as evidence of higher overall output.
Count only the bonuses that apply
Blizzard Strayer’s four-piece bonus gives conditional CRIT Rate against Cryo-affected targets, with an additional bonus against Frozen targets. These conditions are not interchangeable. A target that cannot be Frozen cannot supply the Frozen condition merely because Hydro and Cryo are present.
Weapon, artifact and talent bonuses may apply only to a damage type or target condition. Kaeya’s C1 applies to Normal and Charged Attacks against Cryo-affected opponents; it is not a universal Burst CRIT bonus.

Compare the complete stat change
Ordinary CRIT chance cannot exceed 100%. Extra Rate beyond that point adds no chance. Count conditional bonuses before comparing circlets or substats.
Ratio advice is a starting heuristic, not a build ranking. An equipment swap may also change ATK, HP, damage bonuses or ER. Recalculate the relevant attack and preserve the ability to execute the intended rotation.
