hi
and I think it's actually 20 times
This quote from the French poet, writer and critic Nicolas Boileau means that it is in the things that we have worked and reworked tirelessly that we can shine and excel.
a bit like running, at the beginning we run slowly and over small distances, and with training we lengthen the distances and the pace.
speed, in the practice of an instrument, comes with work, provided, of course, that you have done some preliminary "ergonomic" work on the position of the body, the hands, breathing, and yes, the study of fingerings (having fingers that cross each other never speeds up the movement) and in this area the advice of a teacher can be essential.
a serious study of the fingerings, calmly, at a slow speed, will be a basis of work, it will be enough to accelerate progressively, at one's own rhythm, to obtain the desired tempo.
good luck
