The original message was '.1f' which appears to be a corrupted format string. The fix correctly uses usage_message, but this suggests there may have been a systematic issue with message formatting that should be verified across the codebase.

Similar to the critical alert, this line was previously '.1f' which is clearly a corrupted format string. The fix correctly uses usage_message.
