Enter your current personal record (PR) and your new time to calculate the percentage improvement in your PR value.

PR Value Improvement Formula

The following formula is used to calculate the PR value improvement percentage.

PR Value Improvement= ((Current PR - New Time) / Current PR) * 100

Variables:

  • Current PR is your current personal record time (seconds).
  • New Time is the time you achieved recently (seconds).

To calculate the PR value improvement, subtract the new time from the current PR, divide by the current PR, and then multiply by 100 to get the percentage.
