The phrase "If in a memory-constrained environment" is a sentence fragment that creates grammatical confusion. The sentence should be rewritten for clarity. Consider: "When in a memory-constrained environment and this setting isn't explicitly configured, the default value is 75%." This provides better flow and clarifies that 75% is the default when the setting is not specified.

Copilot generated this review using guidance from repository custom instructions.
