Keep the test consistent
Use a similar patch of leaves and the same measurement interval for both samples.
Clean all the leaves Upgrade Decision Board
Compare upgrades from repeated before-and-after cleanup samples. No official ranking or hidden statistic is assumed.
This is a measurement tool, not a published tier list
Compare choices from your own before-and-after cleaning-rate samples. The board shows absolute gain, percentage gain, a sample-based order, and optional affordability separately.
Your measured upgrade board
Test each choice over the same sample length. This board ranks observed percentage gain; it does not invent official tool stats or universal S/A/B tiers.

Formula: percentage gain = ((after rate − before rate) ÷ before rate) × 100. Cost is shown separately and does not change the measured efficiency rank.
Confidence improves when repeated samples produce a similar rate change.
Repeat uncertain results
A second sample helps distinguish a real improvement from route variation.
Record the date
An update may change observed behavior, so treat older measurements as historical.
