Test Method

Results are cumulated and averaged over the time period between the first tested and last tested dates. I send automated daily* requests to the PSI API for both mobile and desktop strategies, add the latest result for each strategy to its corresponding existing tally, then divide the tally by the number of times the test was performed, and round it to the nearest integer.

Formula: result ≈ Σ[day results] / times tested to date where ‘≈’ means rounded to nearest integer

* Additional tests are occasionally performed between the scheduled daily runs, so the times tested to date rubric will most likely not correspond to the number of days between first tested and last tested.
