R-0871 Taylor Reagent

I'm in the process of ordering new R-0871 reagent from Taylor does anyone know when you take a pool water readings with outdated reagent does it normally test lower or higher results?

If the FAS reagent is compromised, it will take more drops of reagent to get the same results (assuming your DPD indicator powder is not compromised as well). Therefore you will get a false-high result.
