you meant each client can only have 3 entry guard candidates?
how many entry guards are there in the whole tor network and how are they

actually there are many good conference papers presume that the attacker
takes control of an entry node and exit node, then blabla.....

so maybe their assumptions are just wrong at the beginning!?
