we have no idea which approach will work best until it is attempted.
this is 6+ months away.

at that time Jeff Bush's metric pixels/clock will be applied.

if the number is too low, we evaluate and redesign.

unless we have an expert who has done precisely this in exactly the
same field and has significant world leading experience there is
nothing that we can do except follow that approach.

therefore guessing or speculating which might be better is of no
value.  *we don't know*.
