How to interpret biorhythms readings

Each biorhythm is zero when you are born, then it changes by a sinus-like law with the period equal to specific number of days depending on the rhythm (physical - 23 days, emotional - 28 days, intellectual - 33 days).

At any time each biorhythm is between -100% and 100%. Closer to 100% is better, closer to -100% is worse. The color of the circle shows this number visually, for example: pure green is 100%, green-grey is 50%, red-grey is -50% and pure red is -100%.

Special attention should be paid when the biorhythm is 0% or close to 0%. The days when the sign of the biorhythm is changed are called critical days, the circle becomes special . It was observed that people make many more mistakes on critical days.
