Can tape over the probe cause erroneous readings?

Very interesting.

I need to find out how Wagner has redesigned the test probes now that the requirement for a full sleeve is in effect. The previous probes would breathe, they have holes in them, but are they designed to breathe a certain percentage to mimic porous concrete?

If they allow moisture to escape from the test hole, how will 3 month old tests correlate with new tests?
