Interesting that you add the x .85 at the end of the usual formula. When I was undergoing stress ECGs at the CAA facility at Gatwick at around the age of 55 they were quite happy to see my BPM at 180 during the test. That would be way above that calculation.
Their maximum may have been calculated using other figures, including BMI, resting BP and BP during the test. Anyway I survived, whatever it was went away and I now no longer need to visit their facility.
