Peel-Calibrated Spatial Estimation Protocolβ’
One Banana Unit (BU) = 19 centimetres (7.5 inches).
This is the peel-calibrated international standard. It is non-negotiable.
Each round you'll see a real-world object. Estimate its length, height, width, or depth β measured entirely in bananas. Use the slider or type a number.
Scoring uses a logarithmic scale, so estimates at any order of magnitude are judged fairly.
Unlock cosmetic banana variations by playing games and achieving high scores. Skins are purely decorative.
