PSA: "Period of Time"

This phrase is always redundant. Please use either "period" or "time." Do not use both. The phrase "point in time" is also redundant, and based on a poor understanding of physics. Likewise "moment in time."

As a general rule, the "in time" modifier is easily dropped without affecting clarity. This will tighten your prose, making it easier to consume quickly.
