Non-physician reviewed stress test results in. Is an MET of 12.1 good?

I threw your results in Grok and below is what it said. Sounds great! Sorry for the copy/paste formatting.

That’s excellent news — congratulations on those stress test results! For a 70-year-old man, this is a very strong performance.
Here’s a breakdown of what your results mean, based on standard interpretations of exercise stress tests (typically using the Bruce protocol):
• No signs of ischemia on ECG — This is the key finding for the primary purpose of the test (ruling out significant coronary artery disease). A negative ECG for ischemia, especially with good effort, is highly reassuring and indicates low likelihood of blocked arteries causing problems during stress.
• Peak heart rate of 158 bpm — The age-predicted maximum heart rate is roughly 150–161 bpm (using common formulas: 220 - age = 150; or more accurate ones like 208 - 0.7 × age ˜ 159). You exceeded or reached near the predicted max, showing good chronotropic response (your heart rate increased appropriately) and that you put in a strong effort.
• Achieved 104% of Stage 4 — This suggests you completed all of Stage 4 (which is a demanding level: 4.2 mph at 16% incline) and went a bit into Stage 5. Stage 4 alone is already impressive for age 70.
• MET score of 12.1 — This is outstanding. METs (metabolic equivalents) measure exercise capacity:
? Average for men in their 70s (from large studies of patients undergoing stress tests) is around 7–8 METs.
? Many men over 75 average closer to 7–8 METs, and even in healthier groups, exceeding 10 METs is uncommon.
? Achieving =10 METs is associated with excellent prognosis — very low risk of cardiac events, often better long-term outcomes than many younger people with lower capacity. Studies show people reaching this level have low rates of ischemia and mortality, regardless of other factors.
Overall, these results indicate excellent functional capacity for your age, no evidence of ischemia, and likely a very favorable cardiac outlook. It suggests you’re in great cardiovascular shape — keep up whatever activity got you here!
Of course, always discuss the full report with your doctor for personalized advice, but this looks like something to celebrate. Well done!

Hey, that's good to learn. My daughter went out with me, yesterday, to walk and run. We did a little over eight miles of probably 35% running and 65% walking. First time she's gone with me. She usually runs alone and runs a lot, like 5-7 miles 3-4 days a week. It was nice to have someone to visit with during this exercise.

MET score of 12 is amazing at any age.

For real? Hoping the cardiologist says the same when I get his assessment. Hoping it's without any, "you tested great, but...."

Know what I mean?
