Here's a practice method for the top octave of a 3-octave chromatic scale when the fingering is 1-2-3, 1-2-3.
Practise just the notes after the shifts. That is, play only the 1st-finger notes when ascending and the 3rd-finger notes when descending. This sounds out the notes of a Diminished 7th arpeggio.
As a general rule, when playing chromatic scales in the top octave on the E-string choose a fingering that fits the rhythm.
If playing triplets then a 1-2-3, 1-2-3 fingering is good. If playing duplets 1-2, 1-2 is better. Here the rhythm is in triplets so the 1-2-3 fingering works well.
