>>how I ended up with a husband who wants medium well.
hmm,,, I suspect things other than meat done-ness affect spousal choice. we're working on close to 50 yrs - and she still not do "pink"
if one ganders the CDC data on - for example - pork incurred trichinosis, not a lot of recent (read: recent by decade) support for the 6,500'F internal temp for "safe pork" - like that has made any difference in my cooking reception.....
even with the oven finish, the flat iron is easily served without a knife - it's tender, juicy, and really good eats.
I'm still playing with the "end results" - I'm thinking to cut the steak in half, giving one half the four minute sizzle, and "my" half a 3 minute sizzle.....
oh, yeah - it's minutes per real live actual "timer" thingie,,,, not a guesstimate....
to a point one can work with the "thickness" thing - the smaller / thinner end will cook "thru" more faster. so far, that theory is not holding up.
