  We provide several examples of bounded Laurent monomials of minors of a
totally positive matrix, which can not be factored into a product of so called
primitive ratios, thus showing that the conjecture about factorization of
bounded ratios stated in [3] by Fallat, Gekhtman, and Johnson does not hold.
However, all found examples satisfy subtraction-free conjecture stated also in
[3]. In addition, we show that the set of all bounded ratios form a polyhedral
cone of dimension $\binom{2n}{n}-2n$.
