Performance index
The Performance Index (Pi) was invented by Technogym to give a concise and easily comparable assessment of performance in a workout.A heart rate monitor must be worn for a minimum of 3 consecutive minutes to obtain a result.
The index is based on a rating scale ranging from 0 to 99. The higher the rating, the greater your aerobic capacity.
If your performance index increases, this means that you are exercising more intensely without increasing your heart rate.
The criteria used to calculate the performance index makes it possible compare tests taken by people of different ages.
The results can only be compared where the exercise duration and intensity are constant.
there is no way to answer this your pi with this answer.
Alpha Omicron Pi.
it is a number 3.14159265358979323846264338327950288... it's just a lot of numbers after that
Circumference = pi*d = 69 inches
pi is not an abbreviation. It is a letter of the Greek alphabet symbol that symbolises one particular ratio.
3.14 is the approximate value of pi. Multiply the diameter of a circle by pi to get its circumference; multiply the square of the radius of a circle by pi to get its area.
"Pi" is a mathematical term for 3.1415926460.. but used as 3.14 to find either the area,circumference,or perimeter of a circle.....
The ratio of the circumference to the diameter of a circle. (3.14159265358979323846264338327950288...)

The PI value depends on the type of equipment being tested and the voltage level. Roughly it shall not be below the value of 2.0
