where life happens, it probably makes no difference whether it is 4 or 5 positions adjusted.
On a case-by-case basis, either way could produce the "better" timing watch.
Since the adjustment limits are so wide (-4 to +6 sec/day), a watch could have wide variability in 5 positions and "pass" e.g. -4, +6, +4, +5, -1. That would give a maximum variation of 10 sec/day from -4 to +6 and average deviation of +2.
I would prefer a watch that has low variability in 4 positions e.g. +1, 0, 0, -1 to give a maximum variation of 2 sec/day and average of zero.
In general, lower maximum variability, lower average deviation and higher number of positions tested is better. As noted before, 4 positions covers enough directions for gravity to have effect on a balance spring i.e. crown left for a right hander is the same as crown right for a left hander
The nit-picking people will talk about "Other" factors of position that affect timing viz varying frictional forces if the weight applied to pivots and other components are different, creeping lubrication etc, so 6 positions is best.....
Movements can be sold in bits (ebauche), semi-assembled, fully assembled, unadjusted and adjusted. That accounts for supplies of 4 or 5 position adjustment labels. In the real world, for what use that you may have planned, at that price point, it makes no real difference to performance.
Chopard do NOT just buy a movement and slap it into a case. Their chronographs are mainly ETA 2894-2 with Chopard finishing and Dubois Depraz chronograph module added. The GMT models have ETA 7754 as base with Chopard finishing.
The important thing is how the pushers feel and timing seconds-hand starts movement, when choosing individual chronographs. This varies from watch to watch of the same model.
