TTP — Time to Pour is the wait from entering the pub to the first sip.

GTT — Guinness Tap Time is the wait from the start of pouring to the pint being served.

Head is the Guinness foam — the collar on the pint.

Atmosphere is the room itself.

The public G score is a one-decimal, taste-led weighted average:

G = (TTP score + GTT score + price score + Head + 2×Taste + 2×Atmosphere) / 8

Timing scores use clamp(13 − minutes, 1, 10). Three minutes is 10 G; ten minutes is 3 G.
