If you want to practice going from the chord to the note, make the complete circuit: chord, note, back to chord.
no doesnt work that way, the neural pathways and muscles used to initiate a movement in one direction are different[because the opposite motion uses different primary movers ie different muscles] vs those to do a movement on reverse this is one of the reasons running backwards fast does nothing to really make you a better faster running in fwd motion w caveat of correction of overuse issues also even w the same movement , context matters , this is why coaches that have tried to have their soccer players practice w weighted balls dont get the results they want in terms of better agility and and fine motor control of the ball when they go back to a std soccer ballthe adaptive response is stimulus specific so if you want to get better at said chord jump you practice the chord jump since you wa t an adaptation response to the stimulus of learning said movement at greater control and speeds
It's a really basic skill man, just practice it as you normally would and you'll be doing it subconsciously in no time.
I have no problem with the jumps, enjoying pieces like Waltzes and rags, however the most practical advice I have seen is "jump fast, play slow"That is, practice in a slow tempo but complete your jumps as fast as if you were playing full tempo, so that your hands are by the notes way before you need to actually press them, giving yourself plenty time to find the right notes if you jump a little too far or too close.Practice your jumps a little slower to give your brain time to understand the distance you're wanting to travel.I don't personally think there's benefit to doing it your way.
