Flying is a mixture of science and art. Rely on one at the expense of the other and it gets untidy. Yes you can fly scientifically by the numbers, approach at x knots, flare at y feet and float for z metres and according to science you will land perfectly.......only you will not.
Landing is probably the most diifficult part of learning to fly because it takes judgement and practice to get it right. It is that mysterious 'feel' that practiced pilots get for the closeness of the ground and the effect of wind, heat and turbulence on your attempt at a greaser.
Live with the fact that you will not 'grease it on' every time but will arrive safely. That is all that is required.
