Except where you can reduce everything to a mechanical test with a numeric result you will get these differences. Even there you get different measures from different evaluations sometimes if you live near the edge. Even with HTML -- you have "valid" html (things that can be checked with a mechanical validator) and "conforming HTML" which means you follow the spec. Not all validators will give you the exact same results --- and if you wanted to check for conformance to the standard -- you can get different interpretations from different evaluators. The guidelines shouldn’t be thought of as a line that you want to just barely get across. as long as your are right on top of the line - you will get normal variation on whether you are on it or over it one side or the other. Instead - use it as in indication of where you should be above -- and then don't get near it. That is the MINIMUM that you must do. Like the edge of a road. You don't want to drive on the edge of the road. If you are above it by any reasonable amount you won't have a problem. Also, look at the REASON that the guideline is in place. If you fulfil the reason - then you will have met the criteria. Remember the techniques are not required. Only the success criteria. Finally, I can find someone who will pass or fail any site if I want to. That doesn’t mean the ruler is bad. Find a good evaluator and go with them or someone they recommend. Then don't press them to figure out how to pass you. Use them to figure out where the edge of the road is - and how to say away from it.
