First af all, phyphox gives you the time that the system provides us for each data point. As already explained, it is almost impossible that these times for the first event coincide with the moment you press the start button – that's why it's called START in L2…
Whatever Science Journal does: they give you values at a far lower rate (reproduced on two smartphones here) and – as already explained – I have no idea what these times mean at all, I would regard these as artificial, not corresponding to sensor events. Could you please elaborate on how this is better for synchronisation? I simply do not understand your point in this regard…
Speaking of synchronisation: as already explained, smartphone clocks are typically not a good time reference, off by seconds or even more. How do you manage to get two data sources into proper time sync for rates of 100 Hz?
