UPDATED: 

• season with 0.7% salt by weight (leave steaks to absorb and come to room temp)
• 120C oven / internal temp target 50C (takes about 15 min from room temp)
• oil the steaks on both sides and sear on cast iron pan.  set aside to rest before slicing
• 58C final internal temp was just right
