Home canning altitude table: pressure time adjustment · case 05

Dial gauge processing times grow with altitude although pressure already compensates.

Member previewVariant 5 · 3 implementations · 8 checks per implementation

Case contract

Above 10000 ft -> "error: altitude out of range". Water bath adds 0 (<=1000 ft), 5 (<=3000), 10 (<=6000), 15 (<=8000), 20 (<=10000) minutes to base, psi None. Dial gauge keeps base minutes, psi 11 (<=2000), 12 (<=4000), 13 (<=6000), 14 (<=8000), above 8000 error. Weighted gauge keeps base minutes, psi 10 at <=1000 ft else 15. Other methods -> "error: method".

Why this case matters

Preserving recipes must lengthen time or raise pressure at altitude to stay safe (toy table).

One recorded failure
