here's how i do the top wp's
get on the ladder center your self to the middle of the ladder (do this crouched is easier)
try to keep straight and centered while doing this bit:
then start climbing backwards lookin at your feet staying in the middle...once near top goto no clip mode and keep climbing until your pass the ladder top to the point where you think the ladder wp will toally clear the top ledge...u croch and place wp
have a look at it if it's the same height or higher than the ledge than it'll work fine
and check how u make connections to the top ladder make it in a way that they cant fall down that ladder
then test it with bots...they'll tell you if it works
usually does for me
for you
here's what i would do (plz dont mind my messy painting i didn't wanna fire up cs
) removing any useless wp's like the one u want to connect to in ladder2 and the one on an angle connection to ladder in ladder 1
in ladder1:
u can use two wp's nearby but make them as far apart as u can even if it means sticking once right necxt tot the wall and the other next to the box
also the incoming wp place as close to the edge connecting to both the top and middle wp...they'll fall and cath the ladder
