Method, inputs, and worked result

Method

  1. 1Calculate raw paid minutes.
  2. 2Apply the configured rule independently.
  3. 3Compare cumulative raw and rounded time.

Inputs used

  • 08:07 start and 16:38 end
  • 30-minute unpaid meal
  • $20 rate and nearest-15-minute rule

Worked example

One row spans 8h31m before a 30-minute meal.

  1. 1.Raw paid time is 8h01m, worth $160.33.
  2. 2.Example rounding gives 08:00-16:45.
  3. 3.Rounded paid time is 8.25 hours, worth $165.

This row changes by 14 minutes and $4.67; it does not prove overall neutrality.

Reproduce: Enter raw timestamps, enable nearest quarter, and export raw, rounded, and delta columns.
