Not driving style.

The pedal height is adjustable via the stopper or cruise control switch if fitted.
The pushrod length is also adjustable, but does not normally require periodic maintenance. If there was a discrpancy beween the pushrod length and the stopper/switch position there could have been excessive 'freeplay' before anything started to wear. There needs to be a small amount of freeplay for the master cyinder to function but if it was excessive the 'hammer' action each time the clutch was operated will increase the wear rate on the clevis pin hole. As it wears, the hammer action becomes more and more increased. There would have been a rapid decline leading up to when I inspected it as there was a good 5mm or more of slop in the clevis pin hole.

To put it in plain language, imagine you're pushing a nail in with a hammer without lifting it off the nail head, then hammering the nail by lifting the hammer 1mm off the nail head each blow, then lift it 10mm, then 50mm....etc.
