There’s a big gap between “you have to complete the task in exactly this way” and “mistake is a mistake, only the end result count”.
I routinely gives full marks if the student made a small computation mistake but the reasoning is correct. My colleagues tend to be less lenient but follow the same principle. I always give full grade to correct reasoning even if it is not the method seen in class (but I quite insistently warn my students that they should not complain if they make mistakes using a different method).
