@br-ke sorry for the misunderstanding! When it comes to placing, I highly recommend you practice by placing the entire chord at once, even if it’s broken up and arpeggiated. This will get your hands used to the spacing and will also lead to better technique. Something I’m guilty of doing sometimes is just placing and plucking one string at a time, which leads to a lot of unevenness and uncertainty when playing. When you have arpeggios that are more than four notes, you can still apply the same principle by placing as much as you can in any given instance.
Practice by playing the sequence of notes as loud chords, then try playing the same notes with a different rhythm, then place the chord without playing while tugging on the strings a little, and then go on to place another.
tl;dr placing things as chords is your best friend
