Sorry, Philippe, but no. The "if some is good more is better" philosophy
does not apply here. For maximum accuracy you should follow the
directions that came with your test kit exactly. The azo dye that is
formed is not very stable and if you wait too long the color will begin to
fade as the dye degrades.
