Turns out that I'm able to run 4.5 mph @ 12% incline with little ill affect, but start getting nauseous when running 5 mph @ 12% incline (Turns out getting nauseous when 'working out too hard' is normal). According to this calculator -> http://42.195km.net/e/treadsim/ -> It seems like I start getting nauseous at about 13 mets. Doing a conversion of kcal/hr to watts, it looks like the 'getting nauseous' point is about 1000 watts continuously. Interestingly, the same calculator suggests I was doing my 1.5 mile runs at around 16 Mets 1.5 years ago. (9mph jog/run on flatland)
I find it highly suspect that running 9 mph on flatland requires in excess of 1000 watts. I should look at other power calculators...
http://www.athleticslog.com/calculate_workpower - Looks like this guy is estimating 354 watts to run 9 mph. Now that sounds more likely.
Man, all I want to know is the watts/power of running 5mph@12% incline. It doesn't feel like I'm breathing particularly hard, but yet I get nauseous, presumably because of the increased blood flow to power those calves/trunk muscles that wouldn't otherwise be needed as much on flatland. It just seems weird I'm getting nauseous, because I wouldn't normally think that running 5 mph@12% incline would be nausea-inducing. But, I don't really have any basis for comparison.
Well, it looks like http://www.exrx.net/Calculators/WalkRunMETs.html is telling me 5mph@12% incline is 12.8 mets, roughly what the first calculator told me. I guess it just isn't accurate for flatland estimates.
That calculator seems to be estimating 9mph@0% incline at 14.8 mets. That's not too far off from the first calculator. I wonder if Mets doesn't directly convert to Watts? Because 354 watts is believable, but 1000+ watts isn't.

Well, this is interesting. Let's fiddle with these calculations.
score = (12 x METs) + (% of maximum predicted heart rate) – (4 x age)
score = (12 x 13) + (100) - (4x30) = 136
It appears I'm in the lowest risk category. Interesting
Doing a quick calculation of what my mom's score /probably/ is (Based on anecdotal reports of her hill climbing capacity on the treadmill), it appears she has a 3 percent risk of death in the next decade according to this. Not bad, of course, I'm assuming she's capable of 7 mets. 5 mets would have a different outcome.
Also, I'm not entirely sure how they decide what mets value to use. Is it the point at which you get nauseous, or is it the point at which st-elevation/st-depression ECG patterns show up?
Following this guy's self-eval, it's the point at which you "give up"/"Can't do it anymore". If that's true, I can probably assume I could do 15 mets, just that I'll be feeling really nauseous as I'm doing it. 13 Mets doesn't 'feel hard' by any means, but I start getting nauseous.
Oh, well, look here: They define when the test is stopped.
Interesting. "Chest pain, dizziness" suggests the test is stopped when cardiac symptoms happen, and nausea is one of them.

score = (12 x 13) + (100) - (4x30) = 136
If you score 100 or higher, you have have a two percent risk of dying over the next 10 years, while those with scores between 0 and 100 face a three per cent death risk over the next decade.
If you have a score between negative 100 and 0 had an 11 per cent risk of dying in the next 10 years, while scores lower than negative 100 have a 38 per cent risk of dying in a decade.

Oh, well, look here: They define when the test is stopped.
The test is stopped once a person reaches the point of exhaustion or develops chest pain, dizziness or heart rhythm abnormalities.
Those who have normal readings and no alarming symptoms while exercising are said to have 'normal' results and typically do not require further testing.
