I'm sorry that you might have considered my commentary as a bad systematic treatment of xorlo.
Even though it is bad, it includes a systematic table of meaning of {lo} with numbers in Section 3.2.1. By applying M=2, N=5 and broda={gerku}, we obtain the following examples:
re lo mu gerku :
two (which are dogs distributively) of dogs that are five
re loi mu gerku :
two (which are dogs distributively) of groups that consists of dogs that are five
re lo'i mu gerku :
two (which are dogs distributively) of sets that consists of dogs that are five
pi re lo mu gerku :
Quantity 0.2 of a part of one of dogs that are five
(It is not a dog but a part of a dog.)
pi re loi mu gerku :
Quantity 0.2 of a part of one of groups that consists of dogs that are five
(It is one dog.)
pi re lo'i mu gerku :
Quantity 0.2 of a part (subset) of one of sets that consists of dogs that are five
(It is a set of one dog.)
