failureTolerancePercentage property
The percentage of accounts, per Region, for which this stack operation can fail before AWS CloudFormation stops the operation in that Region. If the operation is stopped in a Region, AWS CloudFormation doesn't attempt the operation in any subsequent Regions.
When calculating the number of accounts based on the specified percentage, AWS CloudFormation rounds down to the next whole number.
Conditional: You must specify either FailureToleranceCount or
FailureTolerancePercentage, but not both.
Implementation
