Testing a pound of London Broil for beef jerky. 3/8 thickness sliced with the grain. 0.05% ( by my sketchy calculations ) vacuumed ( no tumble ) 29.5 Hg held for 30 minutes. Then into fridge overnight. Plan to dehydrate in my APO 135F dry bulb no steam for 6 hours ( will adjust accordingly )
Going for 30%- 40% moisture loss.
