The fact that a player is very short of time is, to my mind, as little to be considered an excuse as, for instance, the statement of the law-breaker that he was drunk at the time he committed the crime.
Correcting it, I don't know; just shedding the light of day on it is a first major step, being one of the earliest generations not to just accept the words.
See my father knew a lot about music, he played the piano and he would do theory and stuff like that, but I didn't learn anything from him, but I played that for him and he liked it a lot.
