We go by the USDA guidelines for safety reasons.The old thinking (very old) is that pork needed to get up to 165 to be safe. People still pass that on for some reason. Like for steak, 135 is medium rare - still pink (which freaks out the 165 people). I like 135 because I feel that is the best combination of texture and moisture. You may have other preferences.
Pork loin has very little fat, and no connective tissue to break down, so higher temps only harm the end product.
I went by memory and got it wrong. I apologize. I will edit my posts.
We go by the USDA guidelines for safety reasons.
The safe temp for pork is 145 degrees.
If you choose not to follow those guidelines that's fine, but please don't advise others to do so.
This is not personal, it is the policy of SMF to follow the USDA guidelines.

Another USDA chart for Salmonella (in beef), which also has the guideline for 145 with a three minute rest at that temp.
Having lived through severe Salmonella, I'll have mine well done.
