From what i see, It's Tylo-Vall-Laythe-Bop-Pol in order.
The Vall landing is done by leaving the Mothership barely captured, Vall Landing + Ascent takes like 1800 m/s or a little more.
The Laythe lander was dumped, Tylo lander was repurposed for Vall and Bop-Pol.
For Bop and Pol, Mothership went to Bop orbit, then releases a Lander also that lands on Pol without taking The Mothership, Lander Rendezvous with Mothership later on Bop, which later leaves Bop and Joolar system, at least that's what i see. (I'm talking about @Challyss's entry)
Oh, and maybe check up my challenge (in my signature).
