I don't know how test strips work, I have alwyas used the API liquid test kits. From what you say, i would expect that the colour initially is more accurate. The paper is probably altering beyond this period.
You will usually find the API liquid kits less expensive online, at least from some sources; I now buy mine online and save several dollars. The API Master is a good one to start with.
