N = 10^5 -- Reaccumulation is different again! big LR, intermediate-size f., small (2nd) LF → On contrary, a high-energy impact is needed... |

Here, the difference seems to originate from the fragmentation phase! Velocities of particles are upto 2-times larger. The geometry is also different (cf. the orientation of the impact-point 'tail'). |

However, LR is big -- large velocities did not play a role. |
