A lot of the conversation around standard flare technique is relevant to low experienced pilots or new to type. At a certain point, especially when it comes to runways with unusual profiles, restricted visibility, lack of useable horizon etc you need to engage the grey matter to understand which cues are of most use for the particular runway in question and anticipate those cues which might mislead you. There is no magic sauce, the FCTM technique is a good way to develop a baseline technique which is perfectly good for the vast majority of runways under most conditions. Having a solid, consistent technique allows you to adjust as appropriate for particular circumstances.
