I rated a 70.7 with a pack that weighs under 30lbs
The bag and contents are listed in this review thread I did http://glocktalk.com/forums/showthread.php?t=1316001
No navigation.....city dweller, I know my way around very well
Shelter....just a blanket....plenty of structures for shelter
Still going to upgrade the deficiencies though. Thanks for the calculator!
