Whew! Really working at clearing this system. I am down to just 21 Perimeter Checkpoints after clearing all other Complex, Radar and Mag sites.
Found a good exit via a Class 4 WH (i.e. My hub System >> Class 4 >> LowSec) that was 11 jumps from Jita, where the current loot haul netted...(queue drum-roll)
Done for night, not much more in the way of respawning (nor despawning).
