It should reflect the final concentration of the reagent, i.e. a 1:100
dilution of a 10% solution yields final 0.1% solution.  However, if this
is some in-house protocol that has never been published it is usually
worth it to double check with the original creator of the protocol;
strange things happen in writing down protocols.
