i did 1:45 empty lung after reverse packing. but to be honest i did two minutes of hyperventilation before my try at empty lung dive. what i found very weird was if i could do 1;45 with empty lung how come i could only do 3;30 with full lungs and about four packs. thsi goes to shouw that when i am doing full lung statics i am now where near my limits. considering that with empty lungs i did 1;45. right or wrong.?
