In my humble (?) opinion... I wish folks would use the term "suggested" fingering, rather than "correct" fingering. There are indeed suggested fingerings for things. However, that is just what they are: suggestions, which probably should be tried first -- for many people they will probably work well, if not best. No one is going to slam the fall board on your fingers if you find that something else is more comfortable or easier for you to do in a given passage or chord, however.
.Soft fall fallboards have rendered good old fashioned slamming much more difficult.
