Your results are dependent on a number of factors.
The style of training, nutrition, hydration, stress, sleep etc. Each person is different and our lives are all different but the results below have 1 thing in common. That is consistency.
A program can be adjusted to suit the way you feel at each session but your result will always be determined by your ability to pitch up regardless how you feel.
