Significance of mapping Aqualyx injection points?

[Artorius]

I recently did a DIY session of aqualyx in my cheek and submental regions and was wondering how precise the mapping of injection points should be. All points were spaced 1cm apart and in roughly the same areas. However I was wondering if next time rather than map them myself (which was admittedly a huge pain) use a stencil instead. Wanting to defer to someone with more experience to see if it’s worth the extra effort to get something like that, and also to ask whether small inconsistencies in injection points make a difference in the final result.

TLDR: Will small inconsistencies in Aqualyx injection points fry me and is using a stencil worth it to map out injection points more precisely
