S2L evaluations use a 25% consistency rule: your best day can't be more than 25% of your total profit. Live accounts have no consistency rule.
How it's calculated
Largest single-day profit ÷ total profit = consistency %
Example (Core): total profit $3,200, best day $900. 900 ÷ 3,200 = 28%, over 25%. Once total profit reaches $3,600, you're back within the rule.
If you're over the limit
Consistency is checked at the end of every trading day. A day that ends over 25% isn't a Qualifying Day, and you can't pass until you're back within the rule. Keep trading to bring it down, and check your numbers with the Consistency Calculator.
